I have installed CB sub-panels many a times with no problem because I
can disconnect the live wires at the main panel. In the old house I
am fixing, I need to replace the all-fuse MAIN panel with a new CB
panel. Do I need to contact the power company to disconnect the
juice, or is there another way of doing it? I do not want to mess
with the 240 volt supply because it may hurt a bit (i.e., kill me).
BTW: how do certified electricians go about disconnecting the live
wires before doing a similar job? Thanks
