We have a 1969 Fuse box, using 12 gauge copper wire, 100 amp service.

Long story short We were told by our home insurance and home inspection
people that in Ontario (Canada), there are no concerns with inspected
copper wired fuse boxes until they reach 50 years. So we are not rushing
to replace this box. However I wanted to install GFI receptacles for
outside, kitchen, and two bathrooms. There are none in place now. We
also have a 240 volt outside outlet to run a pool motor.

Can GFI work on fuse boxes/panels? if so, does that GFI outlet, when
tripped, mean replacing the fuse? Do all the GFI's have to be on the
same circuit?

Anyone have any advice on this matter?


The most expensive thing to do would be to use GFCI circuit breakers,
assuming you did want to replace the fuse panel. Just install GFCI type
outlets at the areas you want to protect, and do as the others recommend
for the 240 volt pool outlet.


Let me make sure I got this right. If not somebody tell me.

So I can use a GFCI OUTLET and that will give me protection without having
anything to do with the fuse box? It'll trip at the outlet only but offers
protection. I have fuses, not circuit breakers. I don't want fuses blowing
if the outlet trips.

Right. The GFCI outlet trips and you reset it at the outlet. The fuse
doesn't know anything happened.

If I can get protection at the outlet only, on a fuse system, that will be a
safe and sufficient solution? We will replace the fuse box for a circuit
breaker 5 years from now. Until then I want to avoid having to do ANY work
on the fuse box

Yes, it works quite well. Only one GFCI outlet is needed in the circuit and
it can be wired to protect all outlets *past* that outlet on the circuit (or
not - your choice).
