With the earth loop reading, this would be fine with an RCD fitted, take a LN loop test to see if it meets short circuit protection for the device being used, if not just down rate the protection device to suit.
Sorry the Zn neutral loop impedance as to ensure the cable can withstand a short circuit fault as being supplied with a 6mm could have quite a low impedance resulting in a higher fault level.
The position of the main protective bonding conductor to the services where they are considered an extraneous conductive part should be in accordance with BS7671 regulation 544.1.2.
The size of the main protective bonding conductor should be in accordance with BS7671 regulation 544.1.1 and where...
if the main bond is in place though outside, and the submain carried its own earth connected to the main terminal this would also common up all of the bonding, nowadays assuming plastic incomers it would only be supplementary bonding and may not even be extraneous, the electrician on site would...
Yes you are right, this is all we have to go on in the post. If the distribution circuit is from a pme source and the cabling is not buried within a wall less than 50mm then an rcd would not Ben required or am I missing something
The main bonding would only need to installed within the gas floor boxes outside on the consumer side of the stop cock. The main water assuming this would be in the riser position would require a main bond only in the incomer position both sized in accordance to the main neutral. They won't...
