Recent Aluminum Wire questions

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

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!

How many 50 amp RV sites can a 200 amp meter service handle?

hello, how many 50 amp RV sites can a 200 amp meter service handle? assume the last 50 amp space is 260 feet from the meter. I am in west texas, the rvs are large and everyone usually has 2 airconditionersJA: I'll do all I can to help. How long have you been dealing with this?Customer: I have owned the rv park for 4 years now and am convinced the electrical setup is not correct leading to an exaggerated billJA: How old is the system in question? And have you consulted an electrician yet?Customer: I replaced the load center when I purchased the place 4 yrs ago, the breakers were falling apart, the previous owner setup 14 spaces and a water well on one 200 amp service, so in the hot summer I am dealing with very hot breakers that trip. I also replace the well pumps yearly which I have come to believe the damage is due to brown out. I think placing another 200 amp service to share the load will help, but of course I am not an electrician.JA: Do you plan on doing the work yourself?Customer: I plan on doing the manual labor which is any trenching. the other thing I think could do is run wire to another 200 amp meter that only has 4 rvs on it.JA: Anything else we should know to help you best?Customer: I believe the aluminum wire size is in correct on the outer pedastals, the previous owner just kept adding spaces using regular house outlet wire, I know this is part of my problem, I have a total of 5, 200 amp services (meters) for a total of 32, 50 amp services + 4 water wells

I have an electrical question regarding my home addition in

I have an electrical question regarding my home addition in Minnesota. My main electrical panel is in my garage. I installed a 100 amp sub panel off this main panel in my basement. My question is in regard to the ground bar. The box I purchased had a ground bar on the right side of the box - to which I connected the bare / ground wire that routes to my main panel. I'd like to install a 2nd ground bar on the left side of the sub-panel. This would make the wire routing a bit neater and cleaner. Can I do this? Does it need to be connected to the ground bar on the right?

I was doing wiring work in my attached garage. The new 12ga

I was doing wiring work in my attached garage. The new 12ga romex I ran out there was tested hot from the arc-faulted breaker all the way out. Now that I hooked up my outlets, the entire line is dead. I doubled checked the breakers, tripped them, and still nothing. I am perplexed. My suspicion is the Arc Fault breakers which I hate.
