I'll start by saying we just bought a fixer-upper house.
I searched the topic of adding sub panels and a lot of the answers are a bit over my head so I need some advice.
My house was built in the 20's. At some point in the last several years, someone updated the electrical stuff to a familiar breaker system. The wiring looks modern and insulated and it also looks like things are grounded as far as I can tell.
What I want to do is install an electric stove which requires a 50 amp circuit in place of the deathtrap gas oven (it was old, the line to it had leaks, and I like cooking on induction.)
What I have, I think, is 100 amp service in the breaker box. The breaker box is full, no slots to add a 50 amp breaker.
So what do I do? Should I add a sub-panel? Should I yank the existing panel and put in one with more slots?
In my mind I would think I would put the heavy current circuits like A/C, Oven, and clothes dryer on the sub-panel. That's how it was in my last house.
Anything I do, I'll spend the money to have a licensed electrician to make sure it's up to code, but I want to do the actual work myself.
The house is a single family. Two stories for about 1200 sq ft and an unfinished basement. No outbuildings, garages, wells, etc. Gas Heat, Gas Water Heater. Central A/C. electric clothes washer and electric dryer. I want to install a 50 amp electric range as cheaply and safely as possible, but I want to do it right, and of course the wife wants it done right now :) I'll add pictures tomorrow, probably. Current idea is to double check the gauge of the wire that runs to the clothes dryer to make sure it's heavy enough to handle the stove and then beef up the breaker and receptacle, just to get it done fast. If we do that, we will be able to cook, but not dry clothes, so I'll be in the same place in a month or two.
Some additional information. The breaker box is a Challenger brand SLB12 (12-24)CT. 125 amp max. The Main breaker in there is 100 amps. There is already one doubled up breaker in there. I was incorrect, there is one available slot in it. Will add pics soon (they are too big for SE and I need to edit them).
