will a sub panel get me out of this

alwaysoverbudget | Posted in Construction Techniques on October 21, 2007 04:54am

have a house built in74 wired with alum.[not that that is a direct problem at the moment] has a 125 amp general switch box mounted in the closet. not legal by todays standards i know. anyway the buss bars are bad in a couple places and really needs a a new box.

if i go with a new box it can’t be located in the closet [unless granfathered?] so if i turn it around it’s in the middle of the living room wall.that would suck. if i relocate to another wall then i get into jacking with the alum wiring,don’t really want that.

so i’m thinking about either  pulling the breaker for the stove or dryer and plugging in a  60 amp breaker,run 45′ of #2/2/2 plus ground wire to the garage and putting in a 6 space 100 amp box,no main breaker in this box. rewire the dryer and a couple circuits like a dishwasher and bath,both 15 amp to this box to free up a little space in orig box that has a couple bad busses.

am i right in thinking i can’t put a new box in the closet by todays code? does the sub panel idea sound like a way out of this deal?does it have to have a main dissconnect ? maybe someday the house will get a complete rewire and fix some of these problems..       larry

    Your existing panel sounds a little scary to me, what with aluminum wiring and sections of bad busses, in addition to its' location near flammable stuff.

    Is it the main panel? Who's the manufacturor?

    So I don't really like the idea of your keeping it.  Would you consider turning it around into the living room (with a new box of course) and hanging a centerfold over it?

    Anyway, the answers to your questions:  in my area , and my read of the NEC, would not allow replacement of the existing panel in the same location; your plan for a 60a subpanel sounds legal, check the spec's for breaker ratings as other poster said; you don't need a main disconnect in the subpanel; and yes if a man speaks in the forest where there is no woman to hear, he is STILL wrong.

      i'm with you in that first the alum wiring isn't good. in looking at the box i see no problems with the connection at  the breakers. i did go through the house a couple years ago checked and tighten all the connections,and everything seem fine except 1 plug in,i would love to snap my fingers and have new wiring ,but would guess that 5k might not be enough to get it done.

      the breaker box brand is general switches,125 amp. theres no doubt that if the laocation of this box was somewhere else i would replace it,now!

      i have gave it some thought about moving it and using it as a junction box for all the single circuits,but that would entail makeing a  alum/copper connection to get to the new box. thanks larryif a man speaks in the forest,and there's not a woman to hear him,is he still wrong?

        You said, "have gave it some thought about moving it and using it as a junction box for all the single circuits,but that would entail makeing a alum/copper connection to get to the new box. thanks larry"I would not be concerned with the Al/Cu connections in a J-box. The aluminum wiring problems have been with 10ga and 12ga connections to outlets that were not Al/Cu or CO/ALR rated, and with wire-nutted connections to copper wire. Circuit breakers connected to aluminum wires with set screws have not been a problem. There is now a connector for copper to aluminum that uses set screws, so it avoids the wire nut problems. http://www.alcopstore.com/To solve your problem of bad bus bars, you might check out replacement load centers offered by Eaton Cutler-Hammer for old boxes. http://www.inspect-ny.com/electric/Zinscoreplace.htm#Zinscoreplace1
        You might even be able to increase the load capacity if the feeder wires are big enough.BruceT

          thats very interesting way of fixing this and may be a answer.i'm going to do some checking to see if i could make this work because it would fix the buss bar but i think would still let me stay in present location being as it is a repair not a replacement.   thanks larryif a man speaks in the forest,and there's not a woman to hear him,is he still wrong?

    we had a similar situation; fliped the panel from the coat closet to the hallway and hung a picture over it - worked great & passed code
