Hi, The ground floor insulation resistance is very low, and the reading climbs slowly from about 1mo to 4mo. The flooding was bad, as the plaster is wet half way up the wall. Can this be a possible reason? The cabling looks in good condition (grey pvc, old colours) and I have unplugged...

I agree, very poor set-up. I just want to make sure the main bonding is in place, and dont know wether to demand the dining room is pulled appart, or deviate from regs and bond at the first available point of entry. Thanks, Mike.

Hi, This house has had its extensions extended, and now (apparently) the stop cock is somewhere under what is now the the dining room! I can find no evidence of main bonding to either the gas or the water, and whilst looking at the cobmi boiler (in the loft...) I noticed the main water feed...

Hi, In a loft, should junction boxes be left floating (i.e. between the joists) or secured to a joist? Thanks, Mike.

Hi, Can anybody tell me where I can buy 25mm armoured cable? All the places I know stop at 16mm. Thanks, Mike.

Hi, Is there any point looking at the ELECSA or NAPIT Part P schemes over NIC? Does anyone have any experience of them? Thanks, Mike.

If after using that Armeg solid board cutter, is the joint now technically accessible, and therefore OK to junction box?

A nightmare. Running a 10mm cable across a 'decorated' house isnt easy when the customer thinks you are going over the top. Guess it all comes down to experience...

Hi, How often do you come across a property with no main or supplementary bonding at all? The first two houses I have working on have been like this. I thought it was going to be a rare occurence... Regards, Mike.

Thanks!

Hi, House has an external meter and about 15m of pipe before it enters the loft, then the boiler. The bond should be at the point of entry, so is it OK to be that far from the meter? Thanks, Mike.

Would you overlay small csa single core cables within the crimp butt? Regards, Mike.

Hi, I am struggling to understand how a crimped connection provides a better mechanical and electrical connection than a terminal strip. With a double screw terminal strip you can overlay the cables and screw them down tightly. A crimped connection, with say a 1mm single core cable, seems...

Hi, A friends house has a meter on the outside wall, 60amp main fuse, then 16mm tails which run up the wall, across the ceiling, and back down another wall, totalling at least 12 meters! Is this acceptable? Thanks, Mike.

Wow, quite a document, thanks.
