The 50A MCB you have just fitted is too large for the 6mm² cable you have feeding your shower.

Pipe goes under ground and the first place I can see it appear is behind the floor mounted boiler so in theory I guess that is where it enters the property.

I will test oil pipe tomorrow when I return to connect up just to ensure it is connected as I assume it is.

SWA is 6mm² and 3 core so yes I can use armour and 3rd core as you suggest. Thanks for your help EFLI, that makes perfect sense now. I was beginning to doubt myself earlier hence my question as I have never come across anything like this before.

Thats where I was getting confused. Oil pipe runs from out building to house and is bonded as it enters the boiler in the property with 10mm² to MET. No water pipe between house and outbuilding, no other extraneous conductive parts in the outbuilding.

Thanks for the reply EFLI, yes I am planning on TT ing it at the outbuilding but not sure whether I should bond the tank in the outbuilding as in theory it is already bonded to the MET in the main property.

I am currently running a new circuit to an outbuilding in SWA. Incoming supply to property is TNCS and I was going to TT the outbuilding. The property has oil fired heating and the feed pipe inside is bonded at the boiler to the TNCS system, I was going to bond the oil tank/outlet pipe in the...

You need to trace where they grey conductor comes from, if it wasn't connected there it may not be connected at the other end.

Is the fan spinning?

As far as I understand the 18th edition unless you can provide a risk assessment which says the value of goods within the property likely to be damaged by an over voltage is less than the cost of an SPD then one must be fitted in domestic.

Do you mean sleeving to identify it is a live conductor or are you using the bare earth in T&E as the inter connect?

What actually trips? RCD or MCB?

Usually standard pipe thread sizes as you can either fit an element or rad valves if using on a wet central heating system.
