Hi there lads and lassies I've been to a job tonight where the mcb had blown internally after doing the normal checks went to put the cover back on and found the lid was only held on by tape according to the customer due to the screws being lost I'm not happy about this situation due to young kids around and the chance of the tape falling off. Over time I was thinking of the regs 412.2 under containment what's other people. Views on this situation thanks for any help
