Electrical Meter box

herb2relaxSeptember 24, 2013

We just moved into this mobile home. I am in no way interested in touching or trying to redo anything in this box just trying to understand the nature of the wiring. The house we moved from was very old and its outside breaker box had no main turn off switch. I am thinking this one is the same way.

This mobile home has added a 220v socket for a generator and I want an idea if I am back feeding. If that is possible to tell from the wiring.

Hubby wanted to make sure I understood how to do everything that was told to him by the previous owner so we were testing it out when the power went out. Of course a new neighbor came over and started a bunch of questions about it. Then proceeded to bring his father over to keep opening the breaker box to which I finally had to tell them they needed to leave it alone and we would handle any issues with it.

I added a pic of the breaker box. The white wire coming in on the left is coming in from the 220v that was added, the big black wire on the right is the air conditioner, the orange and yellow wires feed out to another little breaker box that was added and goes into the mobile home. The breaker box says it is 220v & sunroom are two 30amp breakers and one 20amp breaker is the water pump. Which the water pump and shed are another two white cables that come in on the left side of the box. The directions for using the generator is to turn off the main breaker in the house and the breaker for the hot water heater. Then plug in the water pump and connect the generator to the 220v and start.

I realize no one can give me a 100% breakdown or tell me it is safe or unsafe. But if someone can tell me what their opinion is I would appreciate it.

It appears to be an older Bryant panel. Other than the fact it is missing the cover (there is a cover somewhere?) and the main breaker appears to be missing a hold down screw, doesn't seem too bad.

The big breaker at the top with the 200 on it, is your main disconnect.

It's hard to see where the wiring that you think is the generator is going. Is that the only wire to the generator plug?

OH, I missed the last paragraph of your mesage.

That installation is illegal and unsafe not just for the generator, but I suspect also for the wiring to the 220/sunroom circuit.

The generator hookup is NOT ALLOWED to rely on you having to manually turn breakers on and off in the right order (without an electric or manual interlock to enforce that) as well as you have a VERY VERY DANGEROUS situation that I bet that generator has 220V present on exposed prongs.

Get an electrician with a CLUE immediately.

This is another picture of where the orange and yellow wire go out to this box.

Yes, there is a cover to the breaker box I was just holding it up to take a picture. I appreciate the information. So it is back feeding? Also just out of curiosity what is exposed prongs? Are you talking about inside the breaker box?

And this is the inside of that extra box. I dont understand the purpose of this box then. Why would they waste their time putting this in if it does nothing?
