How long have you been dealing with this?Customer: I want to up grade my main service panel, that is fed by this disconnect to a 200 amp service and have a smaller sub panel of the service to feed just my shop.

Im adding a 100 amp sub panel to my home. 2/3 with ground

Hi. Im adding a 100 amp sub panel to my home. 2/3 with ground seams to be the acceptable wire even though #2 is only rated at 95 amps. Is this because its very unlikely that one of the 2 bus bars would ever reach the full 100 amps? Is there a calculation used for that? Seams there must be since 2/0 is an acceptable feeder for a main 200 amp panel but it is only rated at 195 amps.JA: I'll do all I can to help. How long have you been dealing with this?Customer: Just starting.JA: Do you plan on doing the work yourself?Customer: YesJA: Anything else we should know to help you best?Customer: I think my question is pretty clear. Let me know if you need more info.

I want to add up to 4 two hundrend amp panels to a

I want to add up to 4 two hundrend amp panels to a residential property. However, there does not seem to be an mult meter-socket which would allow this; unless I goto 8 one hundred panels. It's my understanding that panels over two hundrend amps are for commercial use only (I could be wrong about that). So that means 4 separate meter sockets. I plan to use PVC conduit to run up the side of the house to where the utility can make thier connections. I'm uncertain if I need to run everything in one conduit or if I can run them idiviually each in their own conduits? Also do I need to keep each TOP close together? Then I was thinking maybe I need to group the ends together with a lug capible of holding many cables so there would be only one connection for the utility? Plus I don't know if in Ohio I need to add a disconnect under each meter? My current meter and breaker box are inline with each other (if you could see thought the wall); would the new meter boxes and their associated breaker boxes need to be inline as well?Kind Regards

If I install a 6000W garage heater on a 40amp breaker, can I use a switch like this, so I can cut the power away from the breaker box? The panel is in the basement and this would be in the garage.https://www.amazon.com/Leviton-MS402-DS-Double-Pole-Disconnect-Non-Grounding/dp/B003AU724E/ref=pd_lpo_vtph_60_tr_t_3?_encoding=UTF8&psc=1&refRID=SYGC32BZTY85K9HHSC42

Hi. I am trying to wire up a three-way automic timer(Defiant model # 32648). Here is my delima. I have a red wire that shows a voltage, a black wire that shows a voltage, a black wire that has no voltage and of course a white wire or neutral. I don't know which is the traveler, hot or line. How do I determine this? I have tried several combinations I can get the power to light up the switch but when I turn it on or off nothing happens.

I just bought a house and I found out it has a 2 wire system

I just bought a house and I found out it has a 2 wire system outlet (no ground wire) on every outlet in my bedrooms and living room. And now it won't pass inspection without getting fixed. So, I was wondering, can I replace the old outlet with AFCI outlets or would it be easier to just add AFCI breakers on those circuits?
