Help me build/revive my big 5hp compressor please! UPDATED, pictures!
What's 6' tall, is green, and weighs about 600 lbs?
W@@T, my champion 5hp 175psi 2 stage compressor!
Here's the scoop. The motor/electronics fried at work one day when we lost a phase. It was an older compressor, so they just bought a new t30 IR unit.
It was either build this setup or buy a HF/sears/lowes/HD/ETC 500 dollar compressor (single stage, 3 hp motor, nothing special).
I have remove the old motor, compressor, and ALL The fittings. The inside of the tank has rust (it's 17 years young...), but it does not leak. Overall, the compressor needs some cleaning, but it seems like a sound setup.
I'm going to run COPPER tubing in the garage for the two main air drops. The copper tubing is about 18 dollars per 10 foot section at home depot (it's the thicker M?? grade?, the thinner L?? grade is about 12 dollars per 10 feet).
After doing research, here are the things I'm going to buy. I'd like your input on these (good, bad, use this one instead, bad idea, etc.)
A baldor L1430T 5hp 1740rpm 1.15sf t184 220v 1 phase motor:
The baldor specs on the motor
Ebay link to motor
5hp Siemens magnetic starter
Ebay link for 5hp siemens starter
New pressure switch
Ebay Pressure switch
New tank check valve

New pop off valve

And some new stickers

I plan on running 8-2 NM-B wire to the starter. Home depot seems to have the best price. I've got about a 40 foot run, ebay prices on the wire + shipping are greater than local prices + tax.
I have a FPE (yes, it's a stablok!!) main pannel. Overall, I think I'll be ok for adding a few circuits to the panel. We have a 150 main panel outside. I'll be adding the compressor run, 2 20a cord reel drops, and a seperate switched overhead lighting curcuit. As of now, the entire garage is on one circuit, when she goes, everything goes!
Based on the few hours of reading/research I've done, I think I know what I need to run the compressor. I'm thinking either a 30 or 40 amp 2 pole breaker and 8-2 wire (no 110 on this run, seperate wire/breakers..). Should I run the cable bare in the attic and run conduit to a breakout box on the block wall?
If I understand how the breakers work, the 100+ amps of startup current should not trip a 30/40 amp breaker. The FLA rating on that baldor motor is only 20 amps, even @ service factor, it's only 24 amps. I think if I go a little over on the breaker I'm still ok. The starter has a heater protection circuit in it (that protects the motor from burning up if it's overloaded or stalled right?).
I think I have the compressor mechanics worked out, I need the most help/sugguestions/pointers in the electrical setup area. I'm comfortable working with 220 and understand the 2 hots + neutral + ground setup.
