exporting earth

[bahco]

right lads need a bit of advice which seems to be a bit of a grey area among the sparks ive spoke to.

ok so tncs pme supply, from consumer unit via 32a 100ma rcbo to garge about 20 mtrs away fed it 6mm 3c swa, in the garage 3 way metalclad board 63a rcd main switch 2 circuits, lighting 6a sockets 32a final ring

now the confusing bit, im led to belive you cannot use the earthing system in your house to earth your garage.... reason is your garage is not in the same equipotential zone as your house.

so would i need to install a earth rod for the garage or is it ok as it is?

any help or advice would be great

thanks lads

yeah did think of that, but i thought it would be better putting the 100ma on the house unit, might score some browny points with the nic inspector

I think it is a good idea to have rcd in garage,as maybe someone would need to reset it without haveing to get into house eg ,gardener.
But as for the rcd in the house I don't think you will be getting any brownie points for putting something in that is not reqd.

Not true, no need to use fire rated down lights if 35watts or below...use a fire rated downlight ok for 50 watt.
Now try to get that on board with a council official. You will get brownie points, no matter what lamps are installed

perhaps HIS argument would be that someone could come along and relamp it with 50 watt?
