I bought an old, 2-1/2-story, semi-detached home a while back as-is. It has
old wiring throughout and, due to the way it is constructed, rewiring the
entire house will not be easy (mostly because the side. front, and back
walls are all masonry). It now has 100-amp service with circuit breakers.
Here's what I am trying to figure out. Should I have the entire house
rewired now (including a new service panel, etc), or should I start out by
just having the new service panel put in (probably will be 200-amp service)
and then worry about rewiring rooms etc. later on? I do know that I will
need a permit either way.
If I have the entire house rewired, an electrician I had look at the house
said that means the whole house will have to be brought up to all of the
current codes (outlets every so many feet in the kitchen, outlets every so
many feet in bedrooms, a dedicated line to each bedroom for a window AC,
etc.). He wasn't an easy person to communicate with, so I couldn't get a
clear answer about what would happen if I just had a new electrical service
installed and keep the existing wiring throughout the house.
My concern is really not about the cost. It's about whether getting into
that entire project is going to expose me to a nightmare of regulations and
What I am wondering is, could I just have the service panel replaced and
upgraded and basically just be exposed to the permit regulations related to
that and not be required to bring everything else in the house up to current
codes? In other words, the existing wiring would just be reconnected to the
upgrade panel. If that's how it would work, that's what I would want to do.
Is that how it typically works?
(I am in New Jersey, and I do know that in the end I will need to find out
for sure from the local building inspector, but I am hoping to get some
ideas about it from here first).
