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

Hi Guys, been out of circulation for a while, trust that your all in good health.
Anyone got any thoughts on the use of Mcb's as functional switch's? Just done a periodic inspection on a pub, noticed that the dis board was behind the bar and the mcb's are being used to switch the lights on and off, no light switch's anywhere. Anyone know if BS7671 accomodates this? Imput apreciated Regards AlanD.
