Small fuse panel
Folks have 1950 house with small fuse panel. Has screw in fuses. Maybe 10 circuits. Panel is 12"x15" in size? Wires all come down from above. How would you in stall new larger panel and use existing wires? The wires cannot be stretched? I do not see how the connections to new circuit breakers can be physically made. I asked an electrician and he said he could do it? How?
