Emergency Lighting in Toilet Cubicles

Summary
1. If the toilet has borrowed light and is less than 8m square:
a. There is no need for emergency lighting, however,
b. If there is a cubicle with full height door – therefore closed without borrowed lighting – then the EM lighting would be required in that cubicle.
2. If the overall toilet has no borrowed light,
a. And the WC cubicles do not have full-size doors; there should be at least one emergency outside row of cubicles.
b. If there is a cubicle with full height door – therefore closed without borrowed lighting – then the EM lighting would be required in that cubicle.

Diagram comparing coordination failure and selective coordination between protective devices in an electrical system. The top section shows a 32Amp circuit tripping a 63Amp breaker, causing upstream devices rated 125Amp and 160Amp to disconnect unnecessarily. The bottom section demonstrates selective coordination, where a 125Amp device isolates the fault without affecting upstream devices rated 250Amp and 600Amp.
