Q: Can aluminum wire be used to feed the breaker on a Generac generator?
by Glenn from New Jersey on December 11, 2014

A: Thanks for your inquiry.

When wiring the generator it must be in accordance with local jurisdiction and codes. If ALUMINUM conductors are used, apply corrosion inhibitor to conductors.

Great Buy, Awesome Deal
I looked for weeks, then found this one for the right price..It was at my house in 4 days!..I installed it myself with only miner issues.. Very happy with this unit, I also put the heaters on. Everything works as it should. This is my 2nd unit I've had on 2 different homes and I would do this again..
Pros: Easy To Use, Reliable, High Quality, I'd Buy It Again
Cons: Wiring Skematic To, Small

As a contractor this is the second unit bought and installed for clients. Works great and easy to install. Due to the weather this year unit had to work four times so far and all with out a fault.

20kw Generac
Been wanting to purchase a generator for some time now, then Electric Generators Direct offered a free Generac Pressure Washer with the purchase so that was my sign. I ordered one right away for this deal. Glad I did now when we are away from home we don't have to worry about the power being off while we are away, and coming home to a refrigerator and freezer full of nasty smelling food. Also a good feeling that while we are home we will always have power.

Generac is a very nice generator... more

Gary,
Since this is the basic (steel) enclosure, the fascia is not included and sold separately. The Aluminum enclosure model includes the fascia base trim.

Great Way To Buy A Generator
Generator was easy to order and pay for. Delivered in a timely fashion right to my door. I found out about this service from a friend who bought the same model four years ago. He is very happy with it.

One Of The Best Investments I Have Made.
Power has gone out 3 times since we installed the generator in February 2013. Today (10-13-14), power went out for 15 hours. We were asleep and did not notice when it came back on.

Checked oil after generator shut down, did not burn any. It feels great to not have to adjust your daily life when power goes out. My investment in this generator was well worth the money.
Pros: Durable, Exceeded Expectations, Reliable, High Quality
Cons: Expensive

Very Pleased With Generac 20kw
Generator arrived in great shape shortly after my check cleared. Installation with a licensed electrician was straightforward. First start required access code, which we had not gotten beforehand...bypassed and started in "Manual" mode. Minor glitch (loose spade terminal on starter) needed to be repaired prior to firing up. After repair, the unit started easily and ran smoothly on LP fuel. A start-up checklist on the generator would be helpful.

After obtaining access code,... more
Pros: Features, Easy To Use, Quiet
Cons: Loose Terminal On Starter Prevented Start On First Try

My Generac
I do not normally purchase items on line because I hate giving out credit card information. This was a large purchase on line using a credit card. I was nervous to say the least. Electric Generators Direct and their freight company were excellent. Both keeping me up to date pertaining to order and shipping status.

I definitely recommend ELECTRIC GENERATORS DIRECT. I saved $900.00 ordering from them vs purchasing locally from a big home improvement store. I ran the gas lines myself then... more
