Spot on. Clearly the folks wanting to play hard-ball and tell the potential buyers to pound sand have never sold a home before. Anything reasonable that moves the sell along is on the table. Depending on your situation, for every month the sale is delayed, lots of money can be lost. Keeping a...

The neutral doesn't carry 2x the amps, it only carries the differential (difference) between the two circuits. What makes this work is, THE TWO CIRCUITS MUST BE ON DIFFERENT LEGS WHICH MEANS THERE MUST BE 240 VOLTS ACROSS THE TWO CIRCUITS AND NOT 0 VOLTS. In this configuration the neutral only...

The concern is line size, distance, bends a pressure. Tying in after the regulator would require a large enough regulator to handle the extra demand and much larger pipe for any given distance. If you tie in before your regulator (high pressure) you can go farther distance with smaller pipe...

What you describe is commonly referred to as an "Edison" circuit. Multi-wire circuit is, I believe, the correct term though. How it works is, you use 3-wire (12/3 with ground for example) and run two hots. Each hot must be on different legs. This means 240 volts measured across the hots. One...

Any tax refunds due to installing can bring the payback down. Sent from my iPhone using Tapatalk

Payback depends on usage. In MI, air conditioning weather may not exist or last long. In southern IL, we use ours a lot. Farther south, even more. In my example above, payback would be 7.3 years. Sent from my iPhone using Tapatalk

At $0.12 per kWh, if the units ran 12 hours per day for 4 months out of the year, the lower SEER model would cost $68.43 per year more in electricity. The lower SEER consumes 2.2 more amps, which is 528 watts... which is 0.528 kW. Multiply the kW times the hours you think the units will run...

All you risk is possibly tripping the breaker after a long continuous run. Since the breaker should hold 80% forever, 83% may take a really, really long time... if ever to trip. Sent from my iPhone using Tapatalk

And that is the #1 reason smash-and-trash is used so much. Stop ripping folks off to recycle, and folks will start recycling. The recycling industry is in it for the money, not for the environment. Sent from my iPhone using Tapatalk

I have a 40x30x10 and heat it with two 30k btu portable propane heaters. The classic propane, sit upright on the floor, garage heater. They are plenty. I am fully insulated though. My 18x9 garage door does have some "daylight" where it deals against the framing... so I'm not perfect, but the...

I have a 30x40 outbuilding, with 2x4 framed walls, standard roof with shingles, etc. Walls have standard batt insulation and the attic has blown-in cellulose. I heat it with two 30k btu propane "Reddy Heater" style heaters. They get the place up to 60 degrees pretty quick. Portable, no venting...

If you care, you could just use a 30 amp breaker. 30 amps is pretty damn close to the 125% of the 25 amp draw. Chances are the breaker won't trip during continuous usage. Sent from my iPhone using Tapatalk

In addition, you say "as long as the cable states 75C or 90C." Well, you will not see any markings on NM with a 75C or 90C temperature rating. Sent from my iPhone using Tapatalk

Also, with regard to your "raceway" logic... although it is not a valid argument, even if it was it would be invalid because the "raceway" (the plastic wrapping around the conductors) would be 100% filled with no airspace to allow for cooling. Sent from my iPhone using Tapatalk

If you look at the tables you will see NM in the 60 degree column... and nowhere else. You will also see asterisks next to #14, #12 and #10. Read the comments. If you are wanting to be up to code, use either #10 NM (Romex) or #12 THHN. Sent from my iPhone using Tapatalk
