Service panel installation for residential wiring

This residential electrical circuit picture shows that the service entrance is the cable running from the meter to the breaker box. The electric utility company will put in the transformer, underground line and the meter. In most cases, it is the owners responsibility to run the cable from the meter to the breaker box.

You will need to be sure what size of cables need to be used. Your local Electric Wholesale outlet will know this, but your inspector will also know. It’s most likely something like 1/0 gauge cables. It is Aluminum-clad cable and it is almost as big around as a garden hose.

You will need three cables. Two will be 120-volt lines that connect to each hot bus bar and one will be a neutral line that goes directly to the neutral bus bar in the breaker box.

All the white neutral wires from each circuit will end up in the breaker box and will need to be attached to the neutral bus bar.

Each hot wire will be connected to the breaker of the right voltage and amperage.

The breakers just pop into place.

I just wanted to say that I love your website. My husband and I followed your instructions on building our own home. Most of the work we did ourselves, but not all. We saved $90,000 in labor costs and now have a beautiful home that we own.

I built my own home doing all my own labor. My house costs me around $70,000 for materials. It took me 8 months to build and is about 2,000 square feet. I didn't think I could do it, but your house web site encouraged me. I used all the info you had.

Thank you,

I can't thank you enough for your free information web site about home building. I was looking for Electrical wiring diagrams when I found your site. It was very helpful.

My wife and I lost our home to foreclosure but we kept a plot of land to start over. We are halfway through the construction of our house. Your website gave us hope to start over and build a house with low payments. We are in our late 60's but we find it rewarding to put so much effort into a project that will reward us for years to come.
