He knows my work, he knows I will not cut corners with electrical work. He knows that I will not wire anything up I'm not sure about - without asking. At the end of the day, I might just wire up the rings and radials and leave him to do all switches. I will chase out the runs and fasten back-boxes and lay the trunking/channels.I have no idea what the arrangement is. Its not one I'd get involved in myself though.
