ABC – City, State - Arc Flash Study

Thank you for the opportunity to provide this Arc Flash Study of the electrical distribution

system for the ABC facility in City, State.

The current version (v7.0) of SKM Power Tools Arc Flash modeling, equipment evaluation, short circuit current analysis and over current device coordination software programs were used to determine Arc Flash incident energy levels for this project. IEEE Standard 1584 modeling software and NFPA 70E

2018 edition was used for verification.

We have documented the results of the calculations and models on two (2) drawings based on the facility distribution system. The calculations have been based on data collected during my on-site visit on January 17-18, 2017.

The results contained in this report are based on the design and information available at the time this report was completed. Any changes made to equipment settings or system configuration will invalidate the results contained in this report and may result in a more hazardous condition thus, necessitating a follow-up review of this arc flash study.

The Incident Energy Summary Report and Equipment Evaluation Report provide the detailed results however; the six (6) highlights of this Arc Flash Study are summarized as follows:

1) Utility Fault Current ContributionThe site-specific short circuit fault current available at the primary incoming bus for the incomingutility service to the ABC facility in City was made available from the local utility for this Arc Flash Studyby email from Dan Somebody dated January 25, 2017.

2) Plant Electric Room and Compressor Room Main Buses @ DANGEROUS LevelOperation of the 3000A Main Fused Disconnects fed from utility transformers is indicated asDANGEROUS (>40 calories/cm2). This is not unusual for protective devices located on the secondaryof transformers fed from a utility or at the incoming main lugs of a power distribution center as thetransformer significantly increases the response time of the upstream protective device.

Also, operation of all the protective devices connected to both the Plant Electric Room Main Bus andthe Compressor Room Main Bus is indicated as DANGEROUS (>40 calories/cm2). These DANGEROUSlevels may be mitigated by increasing the working distance to enable the use of AF PPE Category 4. Seethe notes on the arc flash model drawing for details. Handle extensions may be available to achievethis increased working distance. Remote operation of the switches or circuit breakers may also be anoption to consider.

3) System MiscoordinationThe Incident Energy Summary Report indicates a few areas of over current device miscoordination, seethe (*N5) notations in the arc flash summary report. In a few cases, subpanel branch breakers arecoordinated to the bus duct fused disconnects bypassing the subpanel main breakers.

In an industrial power system, miscoordination is not an uncommon situation to find and it typicallyworks in your favor relative to arc flash as the speed of the upstream protective device reduces theincident energy exposure. These upstream protective devices function in this manner only in anoverload condition. As we understand the system is reliable and functions well, our recommendationis to leave these devices and their settings in their current state. While a detailed system analysiscould be considered, it should be noted that this power system device coordination analysis couldconsume significant engineering and field monitoring cost.

4) Equipment Evaluation ReportThe Equipment Evaluation Report indicates a few failures or marginal ratings. These are primarily intwo areas of over current device ratings in the Device Evaluation Summary Reports. One area is theShort Circuit Current Available ratings for a device > 80% SCCA ratings and the other is related toconnected load to the device > 80% for continuous load ratings.

a. In the case of the available short circuit current ratings, these devices are continuous dutyrated and thus they are suitable for the service as designed and intended. This is a softwaredefault value based on the NEC and in this case is not applicable to your system.

b. The second area is relative to connected load greater than 80% and 100%. The softwarecannot determine the real horsepower of a particular motor and assumes it to be 100%loaded.It cannot determine true loading of multiple motors operated in a lead / lag configuration. Itcalculates to 100% load on every device connected. It cannot calculate diversity of loads perthe NEC. This is the only reason you will find a marginal rating on a device due to loading > 80%or a failure rating on a device due to loading > 100%.

5) Equipment LabelingThe switchboard and motor control center (MCC) sections will be labeled to the actual incident energylevels per the requirements of IEEE 1584 and NFPA 70E for testing, troubleshooting and interactingwith the device with exposed energized parts. All disconnects that could require maintenance, testingor troubleshooting will be labeled to the requirements of NFPA 70E 130.5(H); extracted text fromprovided next.

NFPA 70E, 2015 Edition (Pg. 28)130.5 (H) Equipment Labeling. Electrical equipment such as switchboards, panel boards, industrial controlpanels, meter socket enclosures, and motor control centers that are in other than dwelling units and thatare likely to require examination, adjustment, servicing, or maintenance while energized shall be field-marked with a label containing all the following information:

(1) Nominal system voltage(2) Arc flash boundary(3) At least one of the following:

a. Available incident energy and the corresponding working distance, or the arc flashPPE category in Table 130.7(C)(15)(A)(b) or Table 130.7(C)(15)(B)for theequipment, but not both

b. Minimum arc rating of clothingc. Site-specific level of PPE

Exception: Labels applied prior to September 30, 2011 are acceptable if they contain the available incident energy or required level of PPE.

The method of calculating and the data to support the information for the label shall be documented. Where the review of the arc flash hazard risk assessment identifies a change that renders the label inaccurate, the label shall be updated.

The owner of the electrical equipment shall be responsible for the documentation, installation, and maintenance of the field-marked label.

6) Operation of Electrical EquipmentThe motor control centers and distribution panels are typical lockout points. The calculated energylevels as indicated on the drawings are often in excess of 1.2 calories/cm2 and as such would requiresome level of arc rated PPE.

NFPA 70E, 2018 Edition (Pg. 24)130.2 Electrically Safe Working Conditions(a) Energized Work(4) Normal Operation. Normal operation of electric equipment shall be permitted where all of thefollowing conditions are satisfied:

1) The equipment is properly installed.2) The equipment is properly maintained.3) The equipment doors are closed and secured.4) All equipment covers are in place and secured.5) There is no evidence of impending failure.

Informational Note: The phrase properly installed means that the equipment is installed in accordance with applicable industry codes and standards and the manufacturer’s recommendations. The phrase properly maintained means that the equipment has been maintained in accordance with the manufacturer’s recommendations and applicable industry codes and standards. The phrase evidence of impending failure means that there is evidence such as arcing, overheating, loose or bound equipment parts, visible damage, or deterioration.

NFPA 70E, 2018 Edition (Pg. 35) Table 130.7(C) (15) (A)(a) Arc Flash Hazard Identification for Alternating Current (ac) and Direct Current (dc) Systems

Task Equipment Condition* Arc Flash PPE Required

… Normal operation of a circuit breaker (CB), switch, contactor, or starter

All of the following:

The equipment is properly installed The equipment is properly maintained All equipment doors are closed and secured All equipment covers are in place and secured There is no evidence of impending failure

No

One or more of the following: The equipment is not properly installed The equipment is not properly maintained Equipment doors are open or not secured Equipment covers are off or not secured There is evidence of impending failure

Yes

NFPA 70E makes it very clear the determination of this condition can only be made by the responsible person in charge of the facility. If the facility has evidence and documentation as per the requirements of NFPA 70E 205.3, 205.4 and 210.5 that all five conditions are met, then no arc rated PPE would be required to operate disconnects with the doors properly closed and latched. "In our experience, it is very rare that equipment is maintained to the exact specifications of the manufacturer”. For reference see NFPA extracts listed below.

A safer approach could be taken. Other facilities with similar situations provide an appropriate Arc Rated switchers coat, face shield and leather gloves in each of the MCC rooms and then instruct the task qualified workers when performing the lock out procedure to wear the coat, hard hat, face shield and gloves to interact with the disconnect in question. If this approach is taken, the under layer clothing shall be 100% natural fiber non-melting clothing per NFPA 70E. After the disconnect switch is operated to the “off” position, then lock out procedures can be performed without any arc rated PPE.

NFPA 70E, 2018 Edition (Pg. 44 & 45) 205.3 General Maintenance Requirements. Electrical equipment shall be maintained in accordance with manufacturers’ instructions or industry consensus standards to reduce the risk associated with failure. The equipment owner or the owner’s designated representative shall be responsible for maintenance of the electrical equipment and documentation.

Informational Note: Common industry practice is to apply test or calibration decals to equipment to indicate the test or calibration date and overall condition of equipment that has been tested and maintained in the field. These decals provide the employee immediate indication of last maintenance date and if the tested device or system was found acceptable on the date of test. This local information can assist the employee in the assessment of overall electrical equipment maintenance status.

205.4 Overcurrent Protective Devices. Overcurrent protective devices shall be maintained in accordance with the manufacturers’ instructions or industry consensus standards. Maintenance, tests, and inspections shall be documented.

210.5 Protective Devices. Protective devices shall be maintained to adequately withstand or interrupt available fault current.

Informational Note: Improper or inadequate maintenance can result in increased opening time of the overcurrent protective device, thus increasing the incident energy.

The calculations in this study and resultant incident energy levels are based upon the overcurrent devices (overcurrent relays, circuit breakers, and fused disconnects) operating as designed and being properly maintained. Maintenance intervals should be based on the manufacturer’s recommendations or industry consensus testing standards. This is typically a 3 to 5 year interval based on the conditions of the equipment. The InterNational Electrical Testing Association (NETA) provides guidance documents for adjusting these intervals based on location conditions.

It is important to note that in many cases, changing the trip settings of the equipment in place in the facility is relatively simple to do. Full-function circuit breakers and time overcurrent relay devices often have adjustable long-time, short-time and instantaneous (LSI) trip units that provide the unique ability to modify or change the trip settings with a small screwdriver. As any changes to the equipment settings may have a significant impact on the incident energy levels found in the electrical system, the facility should have a change management process in place to maintain the settings as found for this Arc Flash Study. Any change to the site distribution system or a change by the utility relative to your incoming service fault current could necessitate a review of this arc flash study.

Annex H of NFPA 70E provides guidance for a clothing system to 12 calories/cm2 and as such on all the model drawings anytime there is a PPE Category 3 situation it will be indicated as such with the specific calories/cm2 exposure. This can help you if your clothing supplier is providing 12 calories/cm2 clothing. This needs to be verified to what level of protection your PPE uniform clothing provides. This can be your decision after verification of the ATPV of the clothing supplied, documented and communicated to the affected personnel. Layering of Arc rated clothing is allowed as long as it has been tested as a system. This information is available on the clothing manufacturers’ websites as well as on ArcWear.com. As an example, Westex has tested their Indura Ultrasoft shirt with their T-shirt (typical rental company provided material) and the combination achieves 20 calories/cm2. Tyndale’s 9 calories/cm2 shirt has been tested with various other 4 calories/cm2 T-shirts achieving slightly higher overall results when used together.

Any exposures greater than PPE Category 1 (> 4 calories/cm2) requires the use of an arc rated face shield and balaclava or an arc rated face shield hood assembly.

NFPA 70E requires the arc flash study to be reviewed every five years. If the utility contacts you for a service interruption, ask the question for what purpose. If they are upgrading the transmission line or transmission / distribution transformers, this is your indication to find out what the change will be to your incoming fault current and relay clearing times which can affect the arc flash calculations.

If the utility has not changed anything relative to your incoming service fault current and you have not changed anything in your distribution system on site, then the review can be a very simple process of noting this fact every 5 years. A verification from the utility of the utility information found on the arc flash study document and also contained on the USB drive is all that would be required.

NFPA 70E requires initial qualified training and re-training every three years for your qualified electrical workers. We typically recommend electrical safety training after the labeling activity as this can provide a customized session for your specific equipment and what the labels require as far as proper work practices.

Within the documentation binder for this study are copies of all the associated information; this summary report, the one-line drawings from SKM, the Incident Energy Summary Report, and the Equipment Evaluation Report. All of the relative files in PDF, native Microsoft Office format and native SKM format are provided on an USB drive for file retention. It is recommended that these files be retained in a secure location within your organization. e-Hazard also retains the files backed up to a “secured cloud service”.

I keep an exact duplicate of the documentation binder in my office so if there is ever a question, we can both look at the exact same piece of information at any time in the future. If I should be traveling, I have all the files on my laptop with me.

Please call John Aeiker, 251-581-1492 for any additional clarification relative to this report.
