It seems as though my whole house is wired on one 20 amp breaker, and the rest are just patched in for added appliances as they were added. I need to re wire my house, but it has all sorts of wiring in it, even some exposed stuff with ceramic insulators. I would also like to ad more outlets, but the house has good plaster. Is there a way to fish the wire through the walls? And what would be the proper way to run it the rest of the way to the breaker box?

The exposed stuff with ceramic insulators sounds like "knob and tube" wiring common in the early early days of wiring - before metal clad and non-metallic cable and stuff like that came along.

Separate wires were run inside the walls for live and neutral. They would be passed through joists through ceramic tubes (to prevent chafing) placed in holes in the center of the studs and fastened to the walls and structural members using ceramic insulators called knobs.

Some electrical inspectors say the method is not inherently bad, in and of itself, if it's undamaged, original and undisturbed. It's what was done AFTERWARDS - homeowners adding, splicing and tinkering that compromise it and make it unsafe.

I hate to sound like a broken record but you might want to sit down with a licenced EC, tell him what you want, show him what you have and draw up a plan....especially if it sounds like you're going to need work done starting at the panel (from what you describe).

The most important thing here is to hire an electrician that has alot of experience in this type of work. This is doable with little damage. Maybe ask for references that you can call, or you may know somebody that had this type of work done. Not every electrician can or should do every electrical job.

I agree with electricmanscott.

Who you hire is very important, I consider myself to be a good electrician but I spend my time doing commercial work, if you hire me to do your job, the walls will be full of holes, you want someone who does "fishing" all the time.

A guy who does this allot can really do a good job with little damage, part experience and part intuition for what's in the walls

I would like to add sometimes some damage to walls or ceilings is unavoidable, and you should not be surprised if some patching needs to be done.

Electricians can be good at fishing wires but they are not magicians.
