EICRs - BEST PRACTISE Discussion ThreadEICRs - BEST PRACTISE Electrical Advice

Hi there, I feel this is a bit of a daft question but, we've received a batch of EICRs that are due in June. Apart from one landlord that asked for the test to be as close to the expiry as possible, no-one else has said anything.

I've been helping my "nephew" for the last few years so I suppose the expiry dates are popping up now. What's best practise? Is a month too close?

Morning, I’ve been asked to go it alone by a shop fitter but would need to test & certify each job with NICEIC certification. Is there any way of using a third party registered NICEIC testing company to complete the certs? I spoke with the NICEIC and they state I need two years of previous work to be able to apply?

Jacuzzi bath wiring Discussion ThreadJacuzzi bath wiring Electrical Advice

Should a jacuzzi bath be wired in H07 flex? Wired one recently and spurred off the ring, just took a twin and earth cable off the spur and into a ip65 box under the bath to join onto the flex. But now I’m thinking should I have used h07 flex for this? Maybe over thinking it lol!

Main Bonding with a crimped lug fixing! Discussion ThreadMain Bonding with a crimped lug fixing! Electrical Advice

At college, I was taught that main bonding - such as bonding to a gas pipe - must be carried out using a continuous copper conductor running directly from the Main Earthing Terminal (MET) to the pipework, with no extensions or alterations permitted.

Unknown switch Discussion ThreadUnknown switch Electrical Advice

Does anyone know this switch?
It was used in the 1960s by my father to distribute power to either one or two lamps. In one position, one lamp would burn at full intensity, in the other two at half intensity.
I am interested in the name of the switch and what it was originally used for.
