Gustafson said knob-and-tube was phased out by the 1930s.
As it ages, he said, it will wear down from the current going through it, especially at the connections.
Upgrading to a 400-amp panel, which is what most new homes are being constructed with, will range anywhere from 00 all the way up to 00. Your electrical contractor will be able to procure these for you, usually at a cost of 0-0.
In most cases of upgrading to a 400-amp electric panel (and in some cases a 200-amp panel) you will also need a subpanel or two. You can, however, apply for your own permit and typically save 0-0.
Most homeowners can sleep soundly knowing their electric panels will protect them by tripping off when a circuit overload occurs.
If a private electrician grounds those wires it could pull down many house, or if they were to drop the wires on someones house or accross the street their could be huge liability issues, and it could cost the homeowner money, and the electrician his license. GRM had everything done before the last guy who I called for an estimate even called me back. Though got a 125 amp panel 10 yrs ago for new furnace and A/C unit, had jury-rigged (not by me but by electrician) and split 2/3 of circuits through the years. it's also recessed in the home, the color patch on the stucco wasn't exact but, he told me that in the beginning. 951-675-0725I recently purchased my home that is about 50 years old with an outdated electrical panel that needs replacement. (my husband went bid crazy) We went with Mc Caa because he was the most professional and most importantly he was VERY helpful in explaining all our options.
We had an old electrical panel that was 100 amps recessed in our wall.
(our house was built in the 70's and we remodeled) Mc Caa came out, broke out all the stucco, replaced the panel, pulled the permits, coordinated with our local power provider (PG&E)to disconnect everything and reconnect everything, it passed inspection the first time and the inspectors seemed to know Mc Caa very well.
Now require everything GFI in kitchen with individual circuits for electrical stove and dishwasher. I am looking for a well experienced electrician to replace and upgrade my electrical panel from 60 amps to 200. I would definately appreciate a referral or a search engine to find experienced electricians in my area. I didn't realize we had multiple options because none of the other contractors offered that. He also gave us one flat rate price to do the entire job.
We liked that better than the material and labor quotes we got because those left options open for more money and Mc Caa's quote didn't do that.
History Behind the Walls Prior to the 1900s, builders installed knob-and-tube wiring, said Glenn Gustafson of the Bergen Home Wright, Oradell (bergenhomewright.com).
