I need to clarify something regarding the meter location of

Hi Pearl, I need to clarify something regarding the meter location of service entrance on a residential home. Currently the meter is located between the bathroom window and back door. The pole (mast) is within 13 inches of the bathroom window and 10 inches of the door. I am upgrading service to 200 A using a 2" pole, new 200 A meter box, and 4/0 aluminum wire. Will the NEC 2014 allow me to keep the service entrance (overhead feed) in the same location or will I have to relocate away from the window and door?JA: I'll do all I can to help. How long have you been dealing with this?Customer: Currently the meter is original, aprox. 40-50 years old. Wanting to upgrade.JA: Do you plan on doing the work yourself?Customer: Yes, already have the county permit, meter box, and 2" conduit.JA: Anything else we should know to help you best?Customer: That's it at the moment.JA: OK.

I need to know what size wire will work. I am installing a

I need to know what size wire will work. I am installing a RV plug. It will be a 50amp plug. It will be on its own meter. We have the 125amp meter base with a 100amp main breaker under the meter. I will be hooking the wire to the 100 amp breaker and running it about 110ft underground in a conduit to a second box with a 50amp break and a RV plug. So I was going to use Aluminum wire because it is cheaper. What size AL wire can I safely use for this application?

I am in Oshawa Ontario Canada. Cant find answer to this on

I am in Oshawa Ontario Canada. Cant find answer to this on line, keeps giving answers about wire in cold air Ducts. Question is.. I need to replace/reroute wiring that currently is in basement ceiling but covered up by drywall ceiling.(aluminum wire) 5 circuits.There is a fairly straightforward route to bypass and then abandon covered wire. The hydro panel abuts the cold room under front porch. Is it ok by code to run wire thru cold room (about 12 feet) along 2x10 inch board that already has cold room light wire on it, and then fish wire thru ceiling to get to unfinished area, and does wire need to be covered by U guard or in a conduit? use Romex or BX ?Other option is to take ceiling down and redo after. Wife not to keen on that one.

Problem with power to my circuit breakers, leads are

Problem with power to my circuit breakers, leads are underground. Showing 119 volts at both leads on the pole, distance is 170 ft, both leads at the box in my shop show 123 volts with the main breaker off. As soon as I turn it on, with two small lights in the shop on, voltage drops on one lead to 109 volts and the other raises to 136 volts. My 220 volt heater and 5 hp air compressor work fine, overhead lights work also, but as soon as I try my overhead door opener or bench grinder, both 1/3 hp, neither will work, and overhead lights get real bright. If I turn everything off and try the door or grinder, sometimes they'll work, or not.

Is it against the law besides a licensed electrician to

Is it against the law for anyone besides a licensed electrician to replace a residential 15amp circuit breaker with a 20amp or 30amp circuit breaker? Where is the NEC law written? Is it the Fire Marshal's law? Is it building code? I tried to research this and every link is to a reference book someone is selling... If I was dumb enough to try this myself, could I electrocute myself working in the fuse box? Do circuit breakers snap in and out or do I have to screw live wires to the back? The reason I'm asking: A clueless yahoo tried to sell me a commercial gym treadmill that needs a dedicated 20 amp circuit according to the manufacturer, but he advised switching the circuit breaker myself, even going to 30 amps if I want more things on the same outlet. I know that's wrong. But where does it say that in black and white? What's the law? If I burn my house down, what is the law the insurance company will use against me to deny paying my homeowners insurance claim?

I am building a new woodworking shop. It is located 44

Hi, Jason, I am building a new woodworking shop. It is located 44 inches from my existing garage (both buildings wood sided). I plan to use SER cable to bring power from the existing 200 amp panel in the far wall of the garage, overhead thru the attic space of garage, and then bridge the 44 inches into the attic of the new building and down into the new panel (90 amp service). I am at a loss how to weather seal the buildings around the SER cable. do I run it in metal conduit? If so, do the boxes mount on the outside of the walls, or the inside? I assume I will run a ground wire from the metal down into the new panel to ground them? Thanks in advance. ***** ***** T JA: Thanks. Can you give me any more details about your issue? Customer: Just trying to figure out the best way to protect the cable and weather proof the conduit. JA: OK got it.

I have recently been told that the aluminum wiring, which was up to code when my house was built in 1977, can present a safety hazard over time because it expands and contracts. Yet it is very expensive to replace all the old aluminum wiring in the house with copper wiring. How much of a danger is it? Is it a fire hazard? And is there a way to maintain the aluminum wiring so that it is not a hazard (such as tightening it)? Any suggested solutions? You can respond to***@******.***. Thank you.
