Hey thanks for the video, I am an Electrical Field Engineer, I understand the electrical terminology. However seeing the actual Motor Control Breaker and unit really paints a bigger picture. Allowing me to understand the technician side of the work making it easier for me to understand his side and explain it better in my side. Both fields of study are very important in the Field. Thanks a lot again.

Excellent videos!! Thank You! I am surprised that at my work none of the crew wear Ppe and we deal with 277-480 volts !! I have learned more from you In 10 minutes than I have in a semester or any journeyman at work.
@deadontarget85033 жыл бұрын
That level of PPE is unnecessary at voltages of 480 and lower. I have only suit up like that when dealing with higher voltage busses as an industrial electrician. With that being said, working in an horizontal panel like in the video does present additional safety concerns as he is work over top of the live lines.

Some of our motor controllers have permissives which make it harder to troubleshoot. Especially in our galley where the control circuit is tied into fire switches, dampers, gaylord wash panels which has its own circuit, and fire pull down switches. Finding shorts is a nightmare where no indication of burns can be found, only thing you got is blown control circuit fuses. Thats why its good to learn to read electrical schematics and diagrams.

Dont just meg a motor, ohm it across the windings as well. You can at least give the customer an idea of how much life is left in the motor or pump.

I traced wires and everything seems to be in order. Could a relay be burned in ?
@AccessToPower3 жыл бұрын
Somehow you either have power from your start buttons supplying your coil when the buttons should be open, or you holding relay is closed and immediately energizes the coil. Pull the jumper from the coil to the holding contact off. Turn on power. If the coil closes then the problem is on the start button side of the circuit. If the starter does not start then the problem is on the holding side of your circuit.
