Hi guys Did a IR test on my CU. On my N/E all results were good (>1000) except for kitchen (42.9) lights (44.7) boiler (45.3) shower ( 44.6). I know they all pass but as a lower reading would this indicate age deterioration? Property is nearly 20 years old. Your thoughts please

Thanks Col.Jack that's the part I forgot.

Dear dingbat I am still learning hence why I am still asking. Not once did I say I was competent. Some things I am still unsure about which is why I would rather find out now before declaring I'm competent.

Hi guys, can anyone recommended a cordless hand tool to use as an Electrician? Im looking for one with drill, hammer and chisel . Thanks :)

0.5mm. Thanks for that. Couldn't work out which way round. Regs say operating current of protective device cnt be 1.45 x greater than current carrying of cable. Yet I cnt achieve this,so what do I do?

This is a fictional example. A kitchen ring has a design current of 26a Protection of bs60898 32a Cable will run through 0.5mm of insulation and be installed as ref. 102 in stud wall with cable touching wall. Therefore current carrying capacity= 32x0.88=28a Go to selection of cable...
