Quincy QT5 - How did I do?

[Augus7us]

So I bought a Quincy QT5 that looks brand new, still sitting on a pallet but wired up. Company went out of business and I got it for just under $950 out the door.

Did I jump in to fast here? I want overkill for my compressor. For hobbies I use paint guns, sand blast, etc. Nothing serious though, I like to restore old stationary tools and stuff like that. My old 40gal worked but took forever because I'd have to wait on it. This being a two stage rated at 17.x CFM I'm guessing I wont be needed more air. And I'm hoping this will be the last compressor I buy.

What say you guys? good deal? overkill? Too much scratch?

Oh, I'll get a photo up when I get home.

Pictures!

Does it have the yellow motor or the black one? That is, did you get the 230V or the 208V version of the QT-5?

That's a whale of a nice compressor.

It says 230v single phase on the plate and the mag starter(?).

Another question for you guys. Quincy's site says this has a starting amp load of 28 amps. But someone asked what size breaker and their expert replied 60 amps. Is that right? I'd assume a 30amp breaker, its a five horse motor.

I have a little free time, so here's the photo

That's the one you wanted if you're using it at home. Nice!

Take a look at the Lighting and Electrical sub forum. From research I did there, and independently on the web, I used 40A circuit breaker and #8 NM-b for my 5 HP compressor. The wire is roughly 40 feet long from panel to compressor. But I'm not an electrician, nor do I play one on TV, so your mileage may vary.

40 Amp breaker is fine - 30 would be cutting it too close. IIRC, a branch circuit should never be loaded to more than 80% of its capacity.

Nice compressor - and nice deal - that's what a real 5 HP single phase motor looks like!

I actually zoomed in on the photo beforehand. I didn't want to call and have them update the description to say single phase. I was hoping everyone thought it was 3ph and wouldn't bid

40amp is fine, I'm actually in the process of wiring up my shop before insulating it, so a 40 amp circuit is going into the new compressor room. 60amp would probably be an issue and had me freaking out a bit.

Its starting to sink in, I'll not want for more air, most likely ever! Now the fun part. This thing weighs in about twice what I thought at almost 700lbs... My forklift is on strike and I got the weekend to get it back in service. Good times.

My compressor saga. You got a better compressor and a great deal.

This statement is assuming the pic was taken when it was in service before you bought it. They did a lousy (and not code compliant) job of wiring it. Did you get to see it run? I hope the motor is OK after being run on what looks like undersized wire.

Other than that, you got a great deal!

Definitely sounded like a saga Mick, but looks like it wasn't much of one and you came out ahead in the end. IR was going to be my second choice if I couldn't find a "gently" used Quincy.

Thanks Tommy, I'm happy with it and I did notice that. My thinking is they bought this and set it up in a temp location to get a job done. Then went out of business. That looks like 10/3 to me, hopefully it will run on a 30amp breaker. I'll know for sure next week when I pick it up.

Looks like a very nice compressor. If you got it at an auction hopefully the riggers won't charge $500 to put it on your trailer...

I would attempt to thru-bolt it to the pallet before moving.

Why the desire for a marginal size breaker? Use #10 thhn or #8 Romex and the recommended 60 amp breaker.

You are correct Matt, I'm not sure what's happened lately but rigging fees and premiums have gone up considerable from what I recall in the past.

What's worrying me now is this thing weighs in at almost 700lbs and there was no loading fee. This auctioneer contracts the loading out to a 3rd party and I'm concerned they are going to tell me to load it myself...

Hey Bert, no desire to do it the wrong way. My concern is I'm only running 90amps to the shop and the post on Quincy's website said 60amp! That could be a problem but it looks like what is confusing me is overcurrent(?) protection on startup.

I spoke with a tech at Quincy that seemed knowledgeable and he was saying the NEC says take the startup amps and multiply that by 1.75 and size your breaker based on that number, however he said that 10/3 was fine for the wire because its only rated for 28amps on startup. Which goes along with what I see for wire in the picture.

I've done a little reading on this and found a thread on here that I believe you posted in talking about this. I also saw someone mention that they use a 1.25 ratio to size the breaker. Given my limited understanding of electricity this is confusing me.

It doesn't help that I don't have the unit or a photo of the motor plate, but this is the first I've heard of "oversubscribing" your breaker for startup load.
