an electric meter feeding a house continue to turn after you turn off the main breaker feeding the panel box?JA: How old is the system in question? And have you consulted an electrician yet?Customer: The lady I''m helping has talked to the electric company and they tell her that is normal.

Thank you for your past answers---as it is a big help for

Thank you for your past answers---as it is a big help for the homeowner to understand the electricians calculations. If you answer soon I might not get back to you for several hours, since I am going to our state capitol for something todayNow I've got questions on the service cable size. I see that typically for 200 amp residential services it's either 4/0 Aluminum or 2/0 copper.From the meter to the lower apt. circuit breaker panel I am looking at 45 ft.--and this would have to go through 3 90 degree bends. It looks like the 4/0 aluminum SER is really big, and that would be a real chore to pull that far. So the 2/0 copper cable is smaller (and a lot more expensive at $16/ft) but I guess I could afford it. To get to the upper apt. breaker panel is about 27 feet. (with about 22 feet on the exterior of the house).Questions:1. If the service cable has to go 45 feet from the meter to the breaker panel is it losing it's capacity to carry 200 amps? I have looked for a table to tell me how far this size can carry the 200 amps.. Would I end up having to pay for even bigger SER cable because of the distance.? I have also seen that Home Depot can get from Southwire 3/0 copper cable and it is not that high---$3 per foot. And it is supposed to be good for 225 amps. However, the Siemens Unipak meter bases have a 400 amp bus.2.Does the 2/0 copper service cable also just come in a bundle--- or come in separate strands, too? The Home Depot listing shows it in a bundle of 3 2/0 conductors and one #1. I saw that the aluminum has 3 4/0 conductors plus 1 2/0, but I was unable to see any 2/0 copper service cable in the store. The reason I am asking is I am under the impression that conductors lose some ampacity when they are in an insulation jacket, (i.e. you can't have romex in a conduit.) Between my meters and my breaker panels I think it can be run in 2 inch conduit----I hope they don't have to use 2 1/2---but I believe it would require a conduit body where it enters the house and the 2 1/2 inch ones are really big.3. After I come under the floor I only have 2x6 joist to run between. I am wondering if this cable can be run in that size of joist space exposed or if it has to be in a conduit? I have had different views on that. Then it has to go up into the wall cavity about four feet. So I guess this would be in flexible metal conduit? I've looked at the 2 inch and 2 1/2 inch 90 elbows and don't see how their big radiuses would work at this spot, although they would be used on the outside of the house.4. Regarding the Siemens meter bases, again it is a little confusing to me. They can have 225 amp tenant mainbreakers, but the bus is only 400 amps and the meter bases are 200 amps. Would I not be able to put in 225 amp circuit breaker panels---which it could take because I would have electric heat and perhaps an ondemand electric water heater in each unit. Plus for the lower apartment an electric dryer and a laundry circuit have to be added. So the amps demand is up pretty high. The other option I could consider is having the dryer on the lower apt. circuit, and having a stnandard or hybridwater heater serving both units but powered from the upper apartments panel. That splits up these two heavy loads. Up until now the water heater was on the lower unit panel, with a dryer and range and electric heat, going through the old service! I'm glad nothing burned up! I guess they rewired this in 1950, and by then it had been remodeled into two large apartments, but they just used 100 amp Federal Pacific panels! (They did have some additional fuse boxes for the range and water heater). Thankfully I switched some of the major stuff over to gas in 1992, and took a lot of the electrical load out.You can see what the Siemens UniPak metter base looks like on the Home Depot site. It looks like it should work----but why do they say it can have 225 amp tenant breakers and only 200 amp meter bases?http://www.homedepot.com/p/Siemens-Uni-PAK-2-Gang-225-Amp-Tenant-Main-Breaker-Meter-Socket-WP4212RJ/206109568?cm_mmc=Shopping%7cTHD%7cG%7c0%7cG-BASE-PLA-D27E-Electrical%7c&gclid=CKv_geeL79ACFYhgfgodQekIvw&gclsrc=aw.ds

I own a duplex (1200 sq. ft each unit) which needs to be rewired. I realize that the final load calculations need to be done by an electrician, but I'm assuming even with baseboard electric heat, 200 amp circuit breaker panels would be sufficient. My question is on the service entrance. I went to an electrical supply co. and the best deal they came up with was a CH--2 meter (200a) pack @$896 + 2-200 a breakers @ $667 each = total$2318.Through Home Depot I can get a Siemens UniPak(Mod. # 4212RJ) for $400, plus the breakers are probably a lot less, but these have 225 amp breakers. So will that work with 200 amp circuit panels, or would I need to have 225 amp circuit breaker panels? I'm trying to save money and not buy the $2318 set up. I saw the Siemens UniPak on a similar duplex in this neighborhood. Didn't know it was this complicated!
