I am in the process of building a new home in MN, with a transformer and meter pole already installed (200amp). I also have a 20' utility pole installed which I intend to attach a security light and exterior breaker box to provide power during the construction.Do I need a 200amp rated breaker box with 200amp service?Can I use this as the main breaker box once construction is complete and run underground cable to a sub panel inside the house?What size/type underground cable do I run from meter post to the breaker box?Thanks,Scott

To clarify the connection of the grounded bare from the main

To clarify the connection of the grounded bare from the main panel to the sub-panel in the detached garage, is this bonded to the sub-panel box and the 8 ft buried rods? Also, what is the purpose of the pvc enclosure to the 8 awg grounding electrode connecting the 2 buried grounding rods? All of this seems overkill, and presents considerable work in the field. The feed is behind the fern.

3 yr old front load electric dryer (kenmore elite) - was

3 yr old front load electric dryer (kenmore elite) - was working fine than last night, just stopped, no power - error msgs, anything. Moved washer out of the way & confirmed plus seated tightly. Dryer turned on & seemed to function normally. Before moving washer back into place. . . noticed sparks on back side of dryer when water lines from washer were touching dryer. Is this a grounding issue with a simple fix of relocating water lines or signs of an electrical issue inside the dryer?JA: How old is the system in question? And have you consulted an electrician yet?Customer: 3 yrs old & have tech coming for dryer repair on 10/14, just don't care wait that long & trying to self-diagnose.JA: Do you plan on doing the work yourself?Customer: possibly, just trying to diagnose @ this point.JA: Anything else we should know to help you best?Customer: not that I can think of

The contractor that built my home left much undone.

Hello. The contractor that built my home left much undone. Regardless, as a 55 year old chick, I've become a Sheetrock hanger, tile installer, etc. trying to make it right. Electrical...I want to be safe, of course! So I appreciate your help and knowledge. My exterior outlets don't work. I purchased a digital multimeter with the auto function. I think ousted it correctly...not sure...a working outlet in my kitchen read 3.9...and I got the same result from the non-working exterior outlet. The exterior outlets don't appear to be GFCI...plus...one is located directly in line wth the stream of condensate from a/c located in attic. How can I troubleshoot what the problem is with exterior outlets? I've flipped all breakers...on/off.... Thank you!

I was following your thread where I need to replace a 3 prong plug with a four prong. I went to Lowe's and bought a 30 amp 4 prong for use on a Whirlpool Duet. Not being an electrician I plugged the plug into the outlet to see if the pattern was correct. Since the connection wires were still in the wrapped package I got a quick spark and pop with the electrical smoke smell. I checked our box and one of the A? breakers tripped. What to do? thanksJA: How old is the system in question? And have you consulted an electrician yet?Customer: The house was completed last NovemberJA: Do you plan on doing the work yourself?Customer: that was the plan based on what was on the site here to switch it out - not so sure now if I did damage to the outletJA: Anything else we should know to help you best?Customer: not really

I'm doing a bedroom remodel and trying to figure out why the

I'm doing a bedroom remodel and trying to figure out why the AFCI circuit breaker trips immediately after I try to flip the switch. I've gone over all the connections at all the outlets and junction boxes and finally figured out that an outlet in the bedroom next door is on this outlet (old house). We had all of the electrical redone about 7 years ago, including a new panel. The bedrooms are on AFCI circuit breakers. After some investigation, I found that the bedroom outlet in question appears to be connected somehow to the new bedroom circuit AND the living room circuit. There are 3 black and 3 white wires coming into the box and a pig tails connect to the outlet. If I turn off the bedroom breaker but leave the living room on, all the black and white wires are hot but if I turn off the living room breaker and the bedroom one on, only the blacks are hot. This work is being done with a permit and will be inspected--we had an electrical fire 7 years ago, so I don't want to repeat that! I just don't understand how this outlet is wired and I can't access all the areas where the cable is routed.JA: Just to clarify, are you working with a contractor?Customer: No--the original work was done by a contractor, but we are doing this work ourselves.JA: Do you plan on doing the work yourself?Customer: YesJA: Anything else we should know to help you best?Customer: The outlet was working before the remodel, which I don't understand, since it was on an AFCI outlet.
