    Is the sub-panel indoors or outdoors?

    The Sub panel is actually outside under a deck. It is very accesible but it will always be dry. The wire that I am running will be partially in the attic ( 50 ft) and partially under the house (100 ft). The entire lenth of the wire is in inside!

    If the wire will remain indoors, you should be fine running #2 Alum SER (2-2-2-4). (SER is not rated for outside use)

    Can you explain very accessible?


    Note: Your Non-service rated panel will have to be Nema3R rated.

    Why do you say this Wash? SEU and SER are certainly outdoor rated.


    See NEC 338.10 Uses Permitted

    I did not need to say accessible. I meant that I can get to the panel very easily. Basically I gave more information then you needed. It was irrelevant to my dilema of not knowing the correct wire. The wire is 100% inside the walls of my home. The panel will be accessed from the outside, when needed!

    Thanks for the help

    Sorry, that was a typo!:eek: Thanks Stan!

    That's what I get for not proof reading. I meant underground use.

    Actually (last Friday), I ran 200 Feet of SER--where 100 feet had to be outdoors. What a pain!! :(

    OK, I was caugh slipping--by not reading what I wrote!! :rolleyes:

    I have no idea what this means. If your panel is not located per code, then it cannot be installed. What does it take to get to your sub-panel?

    I have to run approximately 50 linear ft in the attic ( 35 ft above the garage and 15 ft above living quarters) down 8-9 ft. ( in the wall) to the crawl space and then approximately 90-100 ft under the home. The panel will then be installed @ an exterior wall under the Master Bedroom deck which is about 7 ft above the ground. Sorry about my last reply. Most of my reply to you was erased some how!
