ECN Forum Forums General Topics of the Trade Non-US Electrical Systems & Trades Mcb's used as functional switches?

I agree with the comments about Emergency Lighting. I have done a PIR where MCBs are used as functional switching and, although I think its not good practice, have considered that it does not contravene the Wiring Regulations.

I looked at Merlin Gerin data sheets and they say that their MCBs are good for 20000 operations on load.

PS
133-01-01 States "Good workmanhip and proper materials shall be used." So could you say using a MCB as a functional switch is not good workmanship?
