Fake circuit breakers

Seem to be on the increase.

Makes me wonder if we should be testing samples before installation ?

A full and proper test requires relatively elaborate lab facilities, but perhaps a crude test involving say a vehicle battery and a 100 amp fuse.

This wont reveal all faults, but would at least weed out the most blatant "no trip" types.

An MCB tested thus might of course have been damaged, so perhaps test the odd sample and only install untested examples from the same batch. Rather expensive though.

    I have always wondered why MCBs are not tested, at least on initial verification. Perhaps it is too difficult? But we wouldn't install an RCB without verifying its performance.


    However, the chance of getting one of those from Eddie's, Rexel, CEF, Screwfix, etc. must be less than winning Euromillions.
