Posted By Topic: Fire rating consumer mains for safety services

Apr 11 2018 09:18

Is anyone able to clarify if the consumer mains feeding an MSB supplying safety services must be fire rated?

wiring systems associated with safety services shall be capable of maintaining an adequate supply to such equipment when exposed to fire.

What \"adequate\" means will vary depending in part on what the nature of the safety service is.
