I'm a complete numpty and when gardening I've cut the earth wire that goes into the ground outside the front door. I've wrapped the both broken sections together around a metal pin that goes into the wall, but I fear this is not going to do the job and that this is not safe for the appliances inside. Could some kind soul advice what I should do and if I can do it myself. Im a bit strapped and would try like to avoid calling someone else out. Despite this poor evidence to support my case, I am a capable DIYer just not a great gardener. Any advice gratefully received. Thank you
