Customer Questions & Answers

50 amp breaker

Will this handle a 50 amp gfci breaker?
Asked by: cloe
This is NM-B cable. To find allowable ampacity you must use the 60C column of Table 310.16 of the NEC. That table tells us that 8-3 NM-B cable must be protected at no more than 40 amps.

Life of direct burial electric wire

How long is your direct burial pipe rated for? So, how long will your 500 foot rolls of 10/3 wire last when buried. Also, can they be buried with a water line in a trench with sand?
NM-B cable cannot be used outside either above or below grade as all outdoor conduits are classed as wet locations. For your application you could use UF-B cable OR Type THHN/THWN-2 conductors pulled into a continuous conduit system.

Is this a 3 wire plus a bare ground wire, or a 2 wire with a white neutral?

Asked by: Mike
8-3 NM-B cable has 3 - #8 insulated stranded copper conductors (1 Red, 1 Blk, 1 Wht) and 1 - #10 bare solid copper ground conductor.

can this be buried under ground

I need to bury this under ground out to a shed is this safe to bury under ground
Asked by: Sparky
NM-B cable is for indoor dry locations ONLY. Outdoor and underground conduits are classed by the NEC as wet locations so NM-B cable CANNOT be used.

Customer Reviews

500 ft. 8-3 Black Stranded CU SIMpull NM-B W/G Wire is rated 4.9 out of 5 by 10.
Rated 5 out of 5 by from Great Price Significantly cheaper than buying it by the foot from the in-store spool. I was able to get this 125 ft roll for about the same price as it would have been for 75ft off the roll in the store.

Rated 5 out of 5 by from Free shipping made the deal. I had purhased 2 wire from the local HD, then realized I needed 3 wire to keep my project up to local code. I returned the wire and found the local store did not have the 3 wire I needed. When checking online I found I could purchase exactly what I needed directly from the Home Depot online site. It was a few dollars more but well worth it with free shipping. Placed the order and it arrived in 3 days. Project Complete.

Rated 5 out of 5 by from Good Price and Great Service My order was promptly processed and delivered in a couple of days.

Rated 5 out of 5 by from Excellent Value Had bad old aluminum wiring to stove (50A) 60 ft run and dryer (30A) 35 ft run. Was going to buy 10-3 with ground for dryer and 8-3 with ground for stove but it was cheaper and better to buy this quantity and use for both, and have some left over for welder hi amp circuit. Bought a waterhose reel, wound this stuff on, took to attic and used old wires to pull new. Worked like a champ. The blue big box had a similar price but none in stock, HD did have it in stock nearby.
