(iv) where more than one switch is installed on any one building, each switch

shall be clearly marked to indicate the installation or part of the installation which it controls (switch (Reference: Electricity Regulations 1994, Regulation 27(2)(f)).

2.2.3 Regulation 537-04-03:

Where practicable a device for emergency switching shall be manually operated directly

interrupting the main circuit. A device such as a circuit breaker or a contactor operated by remote control shall open on de-energisation of the coil, or another technique of suitable reliability shall be employed.

2.2.4 Regulation 537-04-04 The operating means (such as a handle or pushbutton) for a device for emergency

(ii) have its ON and OFF positions clearly indicated by lettering legible to a

person standing on the ground at the intended site, with the OFF position at the top (Reference: Electricity Regulations 1994, Regulation 27(2)(b)), and

(iii) be provided with a device to prevent the switch being inadvertently
