Urgent - Having problems with electrical hookup

[bohaiboy]

I have everything wired up. A 30 amp breaker. Relay working propery with on/off 110, but when I switch it on, it trips the breaker. Any ideas as to what is happening? Motor never moves, just auto trip of circuit.

Make sure you have the 240 VAC hooked up correctly on the relay. Both wires on the input side should be on one side of the relay and both wires on the motor side should be on the other side of the relay. Check the pictures on this site to make sure you don't have them crossed.

Here is how its wired. Could my leads to the electrical plug be reversed?

Could you send a brief description of your hook-up? It sounds like you are connecting to an outlet. Is it 3 or 4 prong? Which ones are you using, etc? Also, what are the connections at the motor?

Here are pics of the electrical connections. Relay connections next.

L1 is the red and connected to the P1 on the motor
Black is L2 and connected to the T4 and T8 Wires on motor

The other wires are nutted together/

Motor Elec HookUp

I don't see any misconnections in the pictures. Is the ground wire connected to ground (green screw) in the motor box and is the white wire capped off? Do you have a voltmeter? If so measure the voltages at the wall connector. You should see about 120 volts from the ground socket (the odd shaped one or the one that accepts the long prong on the plug) to either of the other pins. Both should read just about the same. Then you should measure about 240 volts between the two non-grounded sockets. If you don't have a voltmeter then take the cover off the outlet and check the wiring to the socket.

I don't have a voltmeter. Maybe just get an electrician out. Would it matter if I have the wiring incorrect in the wall box. Obviously ground is ground, but would it make a differnce if the two live wires were reversed (I don't think so but not an electrician)

Reversing the two hot wires should not be a problem. But reversing one with the ground is. If you feel uncomfortable with it call in an electrician but don't feel uncomfortable asking questions here. We're glad to help.

Ground is where it should be. Thanks for the help.

Can you spin the impeller freely?

 

[bohaiboy]

Sure can. Turns easily both ways.

You might try disconnecting the red and black wires right at the motor, cap them off, and try it. That should isolate the problem to the motor or before. I'm assuming there is a short. Does the breaker appear to open instantly?
