Sub Panel

shocken0

Building a second flr additon going to be runnig a sub panel off the main which is a 100amp service.Going to be feeding the sub with a 60 amp my question is do i need to have a breaker in the sub panel as well.Thank you

If I understand your question correctly, you will have a 60amp breaker at the main that feeds the sub panel in the same building. No you would not need an additional 60amp in the sub panel. Now if it were going to a sepperate structure then it would.

shocken0

yes that was my question thank you for the response.Any suquestions on a panel looking to add about six breakers.

If your load calcs say it is ok. It all depends on what you put on it , but in residential unless you are putting heaters or heavy loads should be alright.

no heavy loads just some bathrooms and bedrooms.One more question i will be purchasing a ge panel should i install a 60amp single pole or a 60amp double in the main service to feed the sub panel and thank you again

Shok, that question about two pole or single pole doesn't make sense, especially from a guy who says his trade is electrical. We must assume your sub panel has both legs so obviously you would want to run both legs.

i am talking the 60 amp breaker at the main that will be supplying the sub panel there will be no breaker at the sub just the main.My question was a single pole 60 amp breaker or a double pole breaker at the main i am learning still and there is lots to learn out there thank you.

homeowner or apprentice...which one?

apprentice just starting out

so is this your first week of being an appentice. I am also guessing you took no training before starting the trade because the question your asking is something a level 1 should know pretty quick.

If I was you I would use a DP in the main and run a 3 wire up to your subpanel. This will give you the option of haveing 240V loads at the subpanel. Unless you plan on putting in baseboards you probably can get away with using a single pole and only being able to have 120V loads at the subpanel.

Then please ask one of your co-workers to give you a hand with your side job. You owe your customer a safe installation. I generally struggle to make the brand of the service panel and the load side panel "match", so that breakers can go back and fourth if need be, and the installation has one model of breaker associated with it.

A 60 amp single pole fed sub-panel is illogical. There is NO reason to do this.
You need a 3-wire (with ground) cable as suggested.
6/3NM would be a suitable cable to run to a 60 amp residential sub-panel.

I also strongly agree that this is stuff you should already know before doing this work on your own!

Do they even make a single pole 60. That is such an odd question I can't ever recall seeing one. If they do I don't know why you would need it, and don't refer back to the OPers question.

Um, if you have to ask something that simple, you shouldn't be doing electrical work on your own.

Make sure those bedrooms have smoke detectors.

Uh OH this question falls in line with Air Pros Beef.

Sparky Joe

Is there even such a thing as a single leg panel?

Like a dog with one front leg missing, every time he tried to lift his leg he fell over. True story. It took him awhile to figure it out.
