This is just a general question, not aimed at anyone's
previous posting.

I have an old, 2-story house, about 1500 sq. ft., built in
1911, with knob & tube wiring and 60-amp service (fuse box).

I was thinking of having the old service replaced with
100-amp service and modern circuit breakers. Will this be
compatible with the existing (old) wiring?

Having said that, I realize that actually replacing the
wiring itself is a BIG job. Does anyone have ballpark costs
on what a job like that prices out to?

Thanks,
