Electrical Question from Adrian about Electrical Wiring for Light Fixtures
Background: Adrian, a Student from Bristol, England
[ad#block]Question: I’m an electrical improver and am about to start wiring a two way intermediate system in a school canteen. There are 15 lights on three circuits ( imagine a rectangle, 3 rows of 5, the first three are emergency fittings on their individual circuit, the next 6 on the second circuit contain one emergency and the final 6 on the last circuit contain two emergencies.) I’m getting extremely confused can you please help explain how to wire it? Thank you

Dave’s Reply:
Thanks for your electrical question Adrian.The emergency lighting fixtures should be on their own circuit, depending on the type of light fixture and if they have internal battery backup or an external emergency power source. You must identify the existing power sources for all light fixtures and then apply the wiring for the desired method of controls. Make a wiring diagram will help you understand the existing wiring that you have identified. The control method may simply be accomplished by using lighting relay contractors that can be activated using a switched line voltage or a lower voltage that can be controlled manually, from sensors or automatically from a programmable controller. It project translates into what the client would like to have and if their budget will allow,  or if a safety or security issue will justify the expenditure.
