I would like to tear out the old knob-and-tube in the garage and put in several interior receptacles, one exterior receptacle, two interior lights, and one exterior light.ġ) Can I just extend a line from the live motion sensor (on the 15 amp breaker) at the side of the house to serve the garage? If that is not big enough – how do I tap the unused 40-amp breaker?Ģ) I imagine I should use conduit to bring the line to the garage below-grade – is PVC ok for that?ģ) I would like to put in GFCI receptacles that are grounded. Only one receptacle in the house appears to be grounded (how is that?). There is a free 40-amp and 15-amp breaker. The motion sensor light is on a 15-amp breaker along with the lights for several rooms. The main breaker for all is only 40-amps. There is another panel in the house with individual breakers. I cannot tell what it services – as nothing seems to die when I kill it. There is a working motion sensor light near the stubbed NM.Īt the house - there is a panel by the meter in the crawl space with only one 15-amp breaker. The stub that has been taped off is dead according to my voltage sensor. There is a newer NM line coming out of the attic running exposed to the garage that has been cut at the house. I have a detached garage with remnants of knob-and-tube that I would like to rewire. but I really don't ever see the trailer utilizing 200amps of service anyway, so I think the occupant has plenty of bandwidth (if thats the right term to say) for power now.

I was very relieved to find that 4/0 can handle 200 amp service when I thought we were running 100amp service.

Not sure why all these photos are showing turned 90 to the left from my phone, but they should be 90 degrees to the right.

I was relying on info from a/c guy and I should've looked myself as I normally do. IF you are dealing with a mobile home, then all other bets are off, you have to use a 4-wire feeder, AND install a separate. with a separate feed to the a/c for mobile home (single wide trailer 15.5ft x 80ft) service. An experienced electrical contractor has told me that you dont have to run the 4 wire feeder but that a 3 wire service entrance cable is allowed provided you do the necessary bonding and grounding at the house. AND it wasn't 100amp service, it was 200amp. even the ground was/is 4/0 and didn't need to be. he had 4/0 cable with 4 big fatty 4/0 cables in it - aluminum. I don't even know the correct "english speaking way" to say "4/0 gauge wire" - do you just say: " 4 slash zero gauge wire" ?Īnyways, to correct this post. I forgot that #4 is different than #4/0 - lol - Big difference. Been a while since I referred to my cable gauges and noted the right terms. but this garage is huge with 10' ceilings, hence my desire to use a sub closer to all the circuits in the house.Sorry to scare everyone. Ps the other way around it is just mount a meter base outside and the main on the inside wall as per usual. the heat pump is outside the house, but i dont think that matters.Īm I reading this right or not? somebody give me some exception to the "entire house" rule if there is one. However, if i do that, then the Entire load will not come from the Sub and i will be forced to use 250 mcm to feed my sub panel. What i WANT to do is feed the A/c Heat Pump from the outside Main panel because it's a straight shot down the side of the house. SER may be used in wet or dry locations at temperatures not to. This WILL work if i run ALL the circuits from fits the definition. Southwire® Type SE, Style SER service entrance cable is primarily used to convey power from the service drop to the meter base and from the meter base to the distribution panelboard however, the cable may be used in all applications where Type SE cable is permitted. What i would like to do is put a mobile home type meter/main on the outside of the house and then feed the main panel (making it a sub panel) from it with 4/0. I guess unless you know the code for allowing 4/0 to feed a 200A panel, you might just say 4/0 since that's what we 'always' use.īut the way i read that exception that allows you to derate the service 83%, the ENTIRE resi load has to come from the panel you are feeding. /rebates/2fp2fSouthwire-By-the-Foot-4-0-4-0-2-0-Gray-Stranded-AL-SEU-Cable-130971992f205001801&.
