Loose earth bond

[JohnD]

Main bonding is required to incoming metallic services (these are usually the water pipe and the gas pipe, but, if present, oil lines, aircon pipes, ventilation ducts, iron or lead drainpipes etc) where they enter your home. They should be connected the main earthing terminal which will be close to, or inside, your consumer unit.

The green and yellow cable size required can be calculated, but in an ordinary house, the calculation is pretty sure to say 10mm, so use that unless you know different.

You do not have to bond metal sinks, windowframes, taps, radiators etc

Post a pic of what you have if you need particular advice.

who (apart from mwatson) can see the words "steel frame building with steel floors, steel ceilings?"

Nobody - including him.

He just makes things up, because he is sad, inadequate and ignorant.

There could be various reasons for you writing nonsense? I don't know which one it is.

Tell us which regulations support your incorrect views?

I wonder if anybody expects him to actually do that, or whether we'll just get more pathetic bluster?

He's not even very good at trolling - trolls are meant to create discord, all he is doing is creating a sense of pity for him, that anybody can have such an empty, unfulfilling and meaningless life that they have to come here and post nonsense to get some kind of validation.
