Question about Air Tools & Compressors

1 Answer

I need a wiring diagram for a kobalt 60 gallon air compressor

The box that houses the wiring comes with the motor already wired to it. The box has two posts empty both marked with ''line''. Do you need a 2 wire with ground 220 volt line or a 3 wire with ground 220 line?

If it's a 220 volt motor, hook l1 and l2 (220 volts) to the line terminals. If it's a'dual voltage' motor (120 or 220)and you want to use 120, hook 120 to the terminals marked 'line'. Make sure the motor is connected for the voltage you're using if it's dual voltage.

    I have a brand new Kobalt 60 as well. No %&$^# wiring diagram on the machine nor online!!! I wired it the way I have read many experts (like the above) describe. I turned the switch to off position. I plugged it in for the 30 minute break-in, but it runs as soon as I plug it in. It is suppose to be OFF!

    Is the switch bad or is it possible that the wiring is incorrect? Do I lug the monstrosity back to the store or not? Please advise.

My 60 gallon kolbalt was running and stop when it filled now it wont go o ever with the tank drain it spins free it does nothing no sounds either

When you say it does nothing do you mean the motor wont come on or the motor comes on and it wont build pressure? if the motor comes on, there are several possibilities:
1. The unloader valve is stuck open
2. The valves in the head are bad
3. The flywheel is loose
If the motor wont come on, the pressure switch is bad (which holds the unloader valve open)

What kind of oil for kobalt 221565 60 gallon

ordinary engine oil 10/30 or 16 oz synthetic oil ( lowes)
There are compressor oils on the market but as the most it has to do is lubricate the bearings and cylinders , engine oil is quite sufficient to do the job as it has all the additives needed to reduce wear , rust and inhibit moisture from the air compression
if it runs 12 hours a day 7 days a week then there will be a service schedule that you should be aware of but if it is just a home operation then every year or two would be adequate for a service

I need to convert mu Puma PPH 30-10 air compressor from 220 Volt to 110 Volt wiring, but I do not have the owners manual or a wiring diagram for it. The Motor is a GE

If this is a 3HP I don't think you can switch it. However there is usually a wiring diagram under the square box on the side of the motor.

How to change clock on intermatic t101p

Step 1:

Turn power off to time clock

Step 2:

Remove the wires, but mark them/label them from where they came from! Should be 4 of them. 2 on the posts marked Line and 2 on the posts marked Load.
Line wires are coming from your power source and will usually have the small white wires with them to provide power to its internal clock motor.
Load wires will go to the motor.

Step 3:

Near the top on the left side you will see a clip style holder. That holds/locks the clock into place. Push up on that clip and with a free hand grab the clock mechanism and pull. The clock should come down and out as you pull.
Take new mechanism and find its resting hook at bottom and just reverse the step above. It should slide into place & lock under that clip. You will hear a click/snap.

Step 4:

Replace the wires that you marked: the 2 Line wires and the 2 Load wires. Check the schematic and ensure that the positions are the same as old or not.
Some older clocks had this schematic: Line - Load, Line - LoadSome newer clocks had it this way: Line - Line, Load - Load

Step 5:

Tighten the screw nice & tight and ensure that you have line wires on the line post and the Load wires on the Load post.
You should be golden.

Replacing the Contactor on my Rudd AC model uaka-037jaz. I got a Dayton 2utl4 contator for a replacement. I need to know which wires connect to what location. I hooked it up with the 2 thermostat wires...

On this unit wiring is very basic, line in wires to the two lugs on the bottom, common as refered to is always black wire which goes to the compressor and the fan motor, red to adjacent lug of the contactor which then one goes to the capacitor and one to the compressor and one to the outdoor fan motor. One wire usually yellow from capacitor to start winding of compressor marked on the capacitor as herm, and a brown wire to the fan motor from the capacitor. The side connectors as you know go to the 24v control coil. The reason as to the fuse going out could be due to loose connections in the disconnect box or a short in the wiring at the compressor, fan motor or capacitor, and worst case a shorted compressor internally. Recommend having the system checked with the proper equipment to include an ohm meter with uf reading ability.

I have a kobalt 60 gallon 3.7hp air compressor, I was using a dryer plug prevousily but I know longer have access to one, the motor says 208-240v is there a way to turn this into 110 or should I just get...

Ya you'll need another motor or a new 240v line. If it were a voltage switchable motor it would say so on the tag. I have an air compressor with a switchable motor and it says 120V/240V on the tag, theres a wire to remove inside the pressure switch to change the voltage.

I have a goodman phkjo48-1 heat pump about 5 yrs old. suddenly no matter heat or air turned on only the fan would come on regardles,the main motor outside would not run. I took off the motor to have it...

Yes Jay, this is what happened. Hopefully you didn't burn out the condenser fan motor you just had tested.Brown normally connects to the capacitor, as this is what starts and keeps the motor running. Hopefully, it just got hot and overloaded to trip the breaker. You say there are 3 wires coming out of a junction box, but you don't remember how they go. @ are hot wires as this motor is 220 volts. Not being onsite with you, and the wires are now faded from the sun, you will need to find out where they connect, ( the 3 coming out of box ) to see which 2 go to most likely they contactor you replaced. They will connect 1 to the load side and the other to the load side but opposite each other. The load side is the side of the contactor that the main 2 hot wires dono't connect to. This is the line side in.If you are sure you wire the contactor right, then it has to be the motor. If you follow the brown wire back, it should go to the run capacitor. Re-check your connections on the motor, even if you have to look at the schematic, which will show you where they connect, and the colors. It should be real easy for you Jay. Get back to me and keep me posted. The new motors have 2 brn wires that go to the capacitor and 2 to 3 going to the load side of the contactor.

What set of screws do i use for the house wires and i have a light i want to connect do i use the wires that r connected to the unit or the second set of screws

Your question is not 100% clear because you don't say exactly what device you are wiring or what wires are inside the box.
You posted under switch-plug combo with GFCI.
Add a comment with clear description if instructions below do not apply to your project.

Electricians don't guess, they test, so lets walk through the steps.

1) If you have GFCI combo, there are markings on back of device for 'LINE' and 'LOAD'.
There are also 2 wires sticking out of back of GFCI.

Lets test your wires.
Separate wires inside box for testing.
Use ordinary 2-wire tester. Tape wood sticks to tester leads to keep hands away from power.
Turn power ON.
Test each wire to bare ground wire.
Tester lights up on Hot wire. Hot wire connects to Brass-colored Line screw.
Hot wire is identified.
Test Hot wire to all other wires, except bare ground.
Tester lights up on Neutral wire. Neutral connects to silver-colored Line screw.
Load wires are wires that go to the fan,light or motor.
Load wires connect to two wires sticking out of back of GFCI device.
Other wires located in electric box could connect to the Load screws, but it is unclear if you have other wires.

2) If you have regular combo switch plug without GFCI, then device has 3 color-coded screws: dark, brass and silver.
Hot connects to dark screw.
Neutral connects to silver screw
Black wire to Load connects to brass screw.
White wire to Load also connects to silver screw
