Hello,
I have a cottage which I am going to upgrade the main fuse box to a Sq D QO breaker panel, 100 Amp to basically keep my insurance company happy. Last fall I built a 20' x 30' shed......now I plan on running power to the shed. The shed is about 100' away from the cottage with another 40' to the breaker panel underneath the cottage and through the crawl space for a total around 150' or so feet.
I was looking at 6-3 w/g uf-b copper, which isn't cheap, with 55-60 amp protection. I have a 6 slot SqD Homeline sub panel in the shed. I plan on direct burial 24" deep.
I found Aluminum quadruplex 4-4-4-4 for about a third of the cost of copper and was considering using it as feed between the two buildings, buying enough Al to bury and then end inside the crawl space, across the floor joists with 6-3 copper to the main panel in the cottage.
After reading up on aluminum wire and its history, it appears it would be suitable for this type use. My main concern is splicing the two. I was wondering if there is an enclosure available with strips similar to power distribution blocks like in a panel where I could terminate the #4 aluminum on one side and #6 copper on the other, both coated w/antioxidation gel plus torqued to the correct values.
I think it would be easier to run copper from under the cottage to the main panel than a bundle of aluminum all the way.
My load in the shed would be some fluorescent lighting, 100 ac outlets for power tools, a radial arm saw and a small 120 or 240 compressor. Nothing real heavy.
A friend who does light electrical work with a local inspector will be helping, plus I will get it bought off. My insurance will require an inspection.
I haven't made my mind up which way to go yet, just looking for opinions.
What do you guys think?
I found a place called wire and cable to go....online.
Sub Panel in Shed and Aluminum Feed
