I have a new mobile home. It has a 200 amp panel. If I use aluminum wire for my service entrance, what size aluminum wire do I need?JA: I'll do all I can to help. How long have you been dealing with this?Customer: Actually, my sister and her husband just bought this double-wide trailer. Okay, her husband says the panel is 200 amps; but he has run 2/0 aluminum wire up the pole. is this OK or does he need to switch to 4/0 aluminum?JA: Do you plan on doing the work yourself?Customer: No. I'm not a licensed electrician. I went to vocational school in the mid 1980's and back then, your could use 2/0 copper for residential with a 200 amp panel; but for commercial, it had to be 3/0 for 200 amp.JA: Anything else we should know to help you best?Customer: What do you need to know? All I know is my brother-in-law has run 2/0 aluminum up his power pole. I'm assuming he has that same wire going to his panel. Should I call him right now?

1956 duplex, appears to still be on original 60 amp service

1956 duplex, appears to still be on original 60 amp service with lots of aluminum wiring. The smaller wires in front of the main entrance cables have been added to allow for a 30 amp breaker to be installed separately from (below) main panel to power the AC compressor. Looks like a problem waiting to happen to me. You thoughts?

Good Evening. Tonight my friend saw a blue and white "spark" come out of the exterior wall of my son's bedroom. On the interior side, near that spot, is an electrical outlet. We saw no sign of burning and no odor. There was a "pop" that accompanied the spark.JA: How old is the system in question? And have you consulted an electrician yet?Customer: Not sure on the first one. The home was built in 65 but I doubt the wiring is that old. As for the second question, it just happened.JA: Do you plan on doing the work yourself?Customer: Not at allJA: Anything else we should know to help you best?Customer: Not that I know of

Dining Room. Two recessed can lights. I am replacing

Dining Room. Two recessed can lights. I am replacing recessed lights with a chandelier which will sit between them. I bought conduit whip. It has black white and green. However, when I disconnected recessed light--the conduit running to it only has black and white (no green/ground). Is there a way to safely connect these two different types of conduits in a box and run the new three wire conduit to chandelier box--or do I need to buy 2 way conduit? Thank you

I'm off grid, I have a solar array and generator and

i'm off grid, I have a solar array and generator and inverter all running from one location.my run in conduit is actually 400 ft. one way. I have the original voltage of 240 through a single throw double pole breaker that is 30 amps down each leg. This is from the inverter breaker distribution. I will need 30 amps down each leg on the far side. I have 1in conduit in the ground already. My questions:1 - do I need to run a ground as I will have ground rods on each side to the panels, do I need to house a ground on this run?2 - wire type THHN but AL or CU?3 - wire size will 4 gauge wire still work?4 - 4 AWG Red, Black, White and Ground or can I down size the Ground to 6 AWG if it is needed?5 - will, what your recommendations are fit in a 1in electrical conduit?Let me know if you need more money to answer these questions. Thank you Ron

I accidently got a package of BX/AC armored cable instead of the MC-Lite metal clad cable I've been using, so there's a small bare aluminum (?) wire instead of the green copper ground wire I'm used to. Can these be used together or do I need to return the BX/AC?

Hope you're having a great day! I have a house with aluminum

Hi Pearl! Hope you're having a great day!I have a house with aluminum wiring - I'm in the process of using Aluimconns (outlets, light switches and lights) to reduce the danger….I just purchased a new stove ( 10.0 KW / 40 AMP ).I have 40 Amp service - I checked my panel box.My old stove was hardwired. Now I need to install a 220 / 4 prong outlet - and hook up the (aluminum) wiring - I would like to to use an Alumicons with this outlet - but I believe I can't BECAUSE for a a 40 amp service I have to use 8 AWG cooper wire and Aluimconns don't work with 8 AWG copper wiring - Alumicons work with + 10 AWG cooper wires.What should I do? Thank you for your assistance.JA: How old is the system in question? And have you consulted an electrician yet?Customer: House built in 1968 - I have talked to several electricians prior to my Alumiconn decision.JA: Do you plan on doing the work yourself?Customer: I have been doing the work myself...JA: Anything else we should know to help you best?Customer: I'm redoing my whole house : ) Thank you!
