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 RCBO breakers. 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
