I have just converted to electric after gas and run a new cable from the meter box to the sub board in the house but now the meter box house power keeps tripping out the breaker in the meter box for the house power when I hook up the black wire from the new wiring into the black link box in the main meter box can somebody tell me is the problem caused because I have the hotwater on the same black as the house power in the sub board

I separated your question from the thread you added to.

I honestly cannot follow your question.

Can you re-word it, using proper grammar and puncutations?

Hi I have sorted it out now thanks
