In the past I have installed type C MCBs on circuits where large motors
would normally trip standard Type B MCBs during start up. Eg in
workshops and garages belonging to woodworkers.
I recently went to get one to fit a Volex CU and see that Volex and a
few other suppliers are only supplying Type C overload protection in
Trouble it Type C MCBs are about £4-5 and RCBOs are nearer £30!
Anyone know why Type C breakers are disappearing? Is it to do with a
regulation change? if so why are other makes still supplying Type C MCBs?
Anyone from the trade know what is going on please?
Secondary question which other makes of MCBs fit Volex CUs
