hi all this is my first post so here goes , i already have power to my garage from my upstairs socket circuit 30A old fusebox type (it was there when i moved in and has been since the sixties ) but it was disused ,i want to fit a new consumer unit in the garage to run a couple of double sockets and some lights so i was thinking of fitting just a double unit with 2 mcb's 1 6A for the lights and 1 30A for the sockets would this be ok , another question is the feed to the garage has 4 wires 1L 1N 1E and one that seems to carry only 33V any ideas what it is and what would i connect this to
cheers
