Hi guys. I Have to take a sub-main to a large external outbuilding. It is basically a domestic garage but larger than some houses that i have wired not that size matters.
The existing house has a TT earth. The garage is a good 30 meters away. Can anyone see a problem with me installing a second spike at the garage and linking it to the house earth as well as a belt and braces type thing or would it be better to keep them separate ? ( I don't anticipate there being any particular problem with getting a decent Ra at either end)
