We have a 240 volt electric motor which operates a lagoon

We have a 240 volt electric motor which operates a lagoon aireator. The motor is controlled by a control box which has a relay and starter capacitor in it. The motor has stopped working. I tested the two motor lead wires for continuity. I read continuity across the two leads. Does this tell me their is a short in the motor? The wiring connection for the motor's pigtail leads is under water but sealed. The motor is two years old bought from Grangers. In the box there is a thermal overload (reset) which one lead runs through. This apparently failed, will not reset. Voltage does not pass through it. Main question is how to test for motor short or failure.

I had some remodeling done in my house which included

I had some remodeling done in my house which included electrical upgrade and so the fuse box in the garage had some additional circuits and breakers added to it. After the remodeling was done and once we got our washer and dryer put back in their locations as they were. The washer works but our LG LDEX8000v dryer does not dry (not heating - the electronic panel gives error code "np" which is supposed to mean "no power". The dryer motor works, i disassembled it and checked the fuses, thermostat switches and heating elements and all pass the ohm meter test. I have not touched the main control board which in my model sit on top of the drum. The Repair Clinic website points me to the main control board being the cause. But since the remodeling work touched my fuse box, i am not sure if the issue is an input power at the outlet. I have a 3-wire connection to the dryer it is supposed to be a 120V from netural to hot on both sides and it is. But when i go from the hot terminal to the other hot terminal, the volt meter reads zero. Is this right, or do i need to have an electrician come and take a look?

To clarify the connection of the grounded bare from the main

To clarify the connection of the grounded bare from the main panel to the sub-panel in the detached garage, is this bonded to the sub-panel box and the 8 ft buried rods? Also, what is the purpose of the pvc enclosure to the 8 awg grounding electrode connecting the 2 buried grounding rods? All of this seems overkill, and presents considerable work in the field. The feed is behind the fern.

I was following your thread where I need to replace a 3

I was following your thread where I need to replace a 3 prong plug with a four prong. I went to Lowe's and bought a 30 amp 4 prong for use on a Whirlpool Duet. Not being an electrician I plugged the plug into the outlet to see if the pattern was correct. Since the connection wires were still in the wrapped package I got a quick spark and pop with the electrical smoke smell. I checked our box and one of the A? breakers tripped. What to do? thanksJA: How old is the system in question? And have you consulted an electrician yet?Customer: The house was completed last NovemberJA: Do you plan on doing the work yourself?Customer: that was the plan based on what was on the site here to switch it out - not so sure now if I did damage to the outletJA: Anything else we should know to help you best?Customer: not really

I am having a problem with my Semens 35 amp GFI. When I use

I am having a problem with my Semens 35 amp GFI. When I use a regular Semens 20 amp braker everything works as advertised. When I use the GFI any thing I use trips the braker even a garage door motor that is not running.I ran a # 10 stranded wire to connect to # 12 solid bx cable for outlets, lights and 2 garage door openers.I disconnected each junction box. When I turn on any light switch on or use an outlet it trips. With every thing connected, as soon as I turn the garage door opener on ( not energizing the motor ) it trips too. ?????
