upper: I shoulda figured that out, will try this weekend. Thanks for the tip.

I've got to "push" a couple of 3/4" conduits under an existing concrete patio slab. Distance is about eight(8) feet. Patio was (reportedly) poured over a layer of compacted coarse sand. There is clear access from both ends. I've used a pressure washer to do this job under sidewalks, but never...

Here's a much larger unit for well under $200.00.

Here's a much larger unit for well under $200.00.

Here's a single-phase to three-phase converter for less than $100.00. Made in America to boot. Perhaps not enough for what's needed here, but might help someone else.

Bueller? Anyone? :o

Five years ago we remodeled an older single-story wood-frame SFD of about 1200sf. We insulated as much as possible and replaced all windows and exterior doors. Heating was by numerous electric wall units which we scrapped. We opted to install a new forced-air heating system consisting of an Aqua...

I'd be much more concerned about the excessive number of copper plumbing fittings and their solder joints.

I am laughing at the suggestion of pulling the conductors out of old BX and pulling new ones in. My suggestion was merely to try that approach as a last resort. The attempt will cost nothing but a little time and (with a lot of luck) it just might work. Interesting that someone would laugh...

What Billy_Bob said. The two existing wires inside of the MC/BX likely are likely really "fat" with old-style insulation. Try this: kill the circuit, carefully disconnect old wires at both ends and see if you can move the old wires back/forth just a little. If you can, I don't understand why you...

Bummer. But at least I've got a lifetime supply of ground wire. Thanks for helping.

I found a new 500 foot roll of #10 THHN at an estate sale and got it for next to nothing. Insulation is green color, however I want to use it not only for ground conductor but for hots and neutral. Is it legal/legit/acceptable to use it in that manner provided that I use appropriately colored...

Thanks all for the information; it's been an experience hearing from each of you. And again, apologies for initial poor explanation of what I'm trying to do. Yes, I'm going to do it anyway but using two neutral conductors as suggested. If I sound stubborn, here's why: Apparently if I was...

Apologies..my original description was lousy. The 20-foot feed to the shed is from a subpanel. Within that subpanel will be a two-pole 20A breaker for my 240V air conditioner circuit and two 20A single-pole breakers for the 120V circuits. So in the conduit to the shed will be (for example) two...

Bringing electricity from main panel to sub-panel @ shed 20 feet away. I'm using #12 THHN conductors in 3/4" conduit with two conductors providing 240V to a dedicated air conditioner outlet and two conductors for two separate 120V, 20A outlet circuits for hand tools, etc. My question is do I...
