What Kind of Electricity Does My Home Have?
Friday, November 6th, 2009If you are buying and selling a home, you will want to understand the type of electricity in your home. It is 100amp? 200amp? What’s the difference?

Electricity
Knowing if the home you are buying has adequate electricity to meet your needs is very important. Your home inspector should explain the electricity set-up in the home you are planning on buying. However, before the home inspector arrives, here is some information that might help you.
How Many Amps
Most homes now are 200 amps. However, some older homes might still have 100 amps service. If you want to check the size of your service equipment, this is very easy. Open the door on the electrical panel and look for the main breaker, usually at the top of the panel. There should be a number on the handle indicating the rated amps. It should say 100 or 200.
200 amp service is sufficient for most of the appliances in your home. However, 100 amp service might not have enough power to be able to handle all your appliances.. If all your appliances were on, (HDTV, computer, toaster, microwave, stove) you would most likely overload your electrical system.
For a buyer, the important lesson is to first check if there is 100amp or 200amp. If it’s 100, then you know that you will most likely need to upgrade. Your home inspector will verify for you.
Knob and Tube Wiring

Some old homes might have Knob and Tube wiring. While this might scare away buyers, it shouldn’t. The problem with knob and tube is that home insurance companies will not insure a home with that kind of wiring. However, you can still buy the home and agree to replace the wiring within 30-60 days. It could cost between $10,000-$20,000 depending on the size of the home.
It would be a shame to pass up a great home, that you might be able to get for $30,000 less that a similar home just because it has knob and tube. Why not buy the home for $30,000 less and then spend $15,000 fixing the wiring. If you do that, you will know that all your wiring is new!
