you only bond metal pipes that could have an earth potential (in direct contact with earth). why not go by 17th edition an install an RCD on the bathroom circuits then bonding is not an issue

Hi Welshy.

On the second link, where it mentions 'inhibitor' in the water I presume they are refering to cental heating inhibitors that are added to the water?

Perhaps if we dispensed with copper and only used plastic, life might be a bit easier?

Although Karlos stated bonding, it appears he is referring to the Main earth which would still be needed for the 17th edition, although maybe not in this circumstance.

NO such thing as a MAIN EARTH. (or do you have a secondary one also?)

do you mean the EARTHING conductor?

sorry to be pedantic, but thats one of the tings gets me wound up.

an earth is an earth,! only one, everything else is connected onto it, so its simply an earth conductor.

or is it a main bond?

which isnt needed if >70% of install is in plastic, including the incomer.

I can never remember the calc for this so i use 70% as a rule of thumb, no doubt someone will correct me. ; \ ; \

All I will tell you is this....... Bond, bond, bond and more bond, then bond some more.

You can never bond enough, cover every aspect you can think of, then bond some more.

Am I getting this accross yet?
