Table 52.3. Could someone explain it to me, again, please!

alanblaby:

I've done an EICR this morning, all in perfect condition, apart from two Code 3's, a plastic CU, and a boiler supply on a 1mm T+E cable.

I've marked it as a '3', as Table 52.3 says a 'power circuit' , should be supplied by a minimum conductor size of 1.5mm.

This circuit is protected by a 6 amp, type B circuit breaker, and further on, a 3 amp BS1363 fuse.

So there is no safety issue at all.


Has it ever been explained why this table has been included, and why these figures are used?

Hi Alan, did the customer specifically request that C3s were specifically recorded or do you provide this extra EICR service for free?
