IR 60 gal Air Compressor oiled

[jdonovan]

Meh.

That pretty well flies in the face of almost every appliance that is plugged into a 120 receptacle. Consider a 60 W trouble light for example...15 amp breaker on a half amp load. Also consider how many appliances have just an 18 gauge cord attached to them, like a vacuum cleaner...still on a 15 A breaker which is matched to the 14 gauge required to feed the receptacles.

The ampacity of 18g conductors in free air is 12 amps. Single appliance draw is limited to 80% of branch circuit capacity when multiple receptacles are fed.

80% of 15 amps is 12 amps.

Hmmmmm almost like they thought this out when they put the US NEC on paper.

actually, the 80% rule means that they RATE circuits at 80% is there continuous purpose. it doesn't mean that there actually 80% of the current. A 15 amp breaker provides 15 amps.

When calculating load, we are only allowed to use 80% of that 15 amps to determine the wattage allowed for use.

Manufactures routinely under-size their wires. everyone knows that.
Ive hooked up chandeliers with twenty (20) - 60 watt lamps (thats 1,200 watts) that are wired with lamp cord (whats that 18-20 ga). you can feel the wires after the light has run for awhile....they get very very warm.

Utility companies also REALLY under size their wires, as there not bound by the NEC rules. I recently completed a commercial 400 amp panel with 350 MC copper riser wires (overhead feed), and the utility dropped a #4 aluminum feed to hook up to them. I KID YOU NOT.

Wow, I didn't realize it would be so complicated to own a bigger compressor. Where would I get a good regular - Northern Tool or Tractor Supply where I buy the compressor. I have been looking at craig's list but haven't found anything close enough to look at.

Also, I find that my shop breaker box is full of breakers.

i was at my local too supply place today, and i say 4 different models from 4 different manufacturers...price range between 900 - $2,400.00.

ALL 4 HAD REGULATORS AND MOTOR STARTERS...NO CORDS THOUGH

I am just a homeowner with 24 acres, tractor, ZTR, mule, etc. Not doing anything professionally at all. This would seem to be a nice upgrade to what I have.

Since this will be for home owner use why not simplify things and get something like one of these Emglo compressors. They'll run a half inch impact or a small sandblaster for short bursts and that satisfies most home owner needs. And above all it's very portable.

Most conductors are now rated for 90c, 194F.... even the old 60c standard was 140F, both of those are really warm to my hand.

#4 AL, eek. Well the good news is it won't glow... it will just melt and drop when they start running the 400A through it.

It seems the more up stream you get the more and more everyone assumes the downstream load will be something less than the 80%, and it all works fine until you get loads that start drawing close to the max.

I recently found the oposite. I was looking at an upsize on my home pannel, and it turns out back in the 70's the local power company ran 4/0 copper everywhere they put in meters. Very shocking to find that on a 200A service.

I looked at the IR units from TSC and Northern. But when I looked closely at the Puma, I couldn't see any difference between it and the IR unit. Neither could the wife or salesman. Except that the stickers, color, and price were different. The Puma was on sale for $399.99 including a regulator and 110VAC power cord. But, it's only a 20gal tank. All I need for my garage. I looked at the 60gal tanks, but just couldn't justify the additional cost.

Whatever you buy, if it be an "oiled" compressor, carefully read and follow the break-in directions.

Alan, I'm not necessarily recommending it to you, but I'm happy with this Industrial Air compressor by Coleman Powermate that I've been using since Sept. 2005. Back then I bought it from Northern Tool for $536.08, including some small air accessories and sales tax. It can be converted to 240v, but I just left it as is and have it plugged into a 120v outlet on a 20 amp breaker. I never move it since I have enough hose to reach anywhere on my property so I have a couple of boards under it to raise it a couple of inches and put an elbow, short pipe to the side, and a ball valve to quickly and easily drain the condensation. I sometimes run it continuously for long periods of time and have never had a problem with it.

Actually I meant where would I get a REGULATOR, same place I buy the unit? Gonna stop by TS today between lunch with Mom (almost 89 years old) and baseball games featuring two of my grandsons.

I'm thinking I want enough volume of air to blow off the shop floor and grass of the ZTR. I realize the turbine blower is going to deliver a much larger volume of air however, for this use. But not as much "pressure" for blowing out a filter etc.

I routinely do that; cleaned the ZTR and the Stihl string trimmer that way a few minutes ago. I also have that 4' air blow gun from Northern Tool to blow out the shop floor, blow off the driveways and sidewalk, and to blow the leaves off the patio. I don't have or need the electric or gasoline blowers the pros have to use. And every time I shave with my electric razor, I step across the breezeway into the shop to blow the whiskers out of it; never had to take the razor apart or use a brush on it. When my wife gives me a haircut, I blow off the hair clippers and blow the hair off my clothes. I frequently blow off the bottoms or soles of my shoes before coming in the house.

And I do use it to blow the dirt and dust off air filters, including the mower, the shop vac, the house vac, etc. I just don't hit it with the nozzle close enough to blow holes in the filters.

I meant where would I get a REGULATOR, same place I buy the unit?

Yes, and they may or may not have a threaded nipple (short piece of pipe) to attach the regulator to the compressor. You may need some fittings from elsewhere or they may have them. Personally, I also have a lot of quick connect couplers. I have one on the compressor itself, then 3 hoses, a paint gun, a 1/2" impact, a 3/8" air ratchet, 3 blow guns, one engine cleaner siphon, the telescoping rain gutter cleaner, an angle die grinder, and I can't remember what else right now.:laughing:
