Why Magnetic Core Balance test is performed only on Star side of Transformer and not on Delta Side of Transformer (Vector Group Dyn11)?1 2387
A simple Question from all.... If Voltage drops then its rated value what will be effect on a Residential load? similarly if voltage rises from its rated value then what will be effects on a load? i know if voltage drops the equipment or device draws more current then its rated what are other reasons ? thanks in advance for ur time.......1 1445

why do motors burn out? I understand why adding parallel loads to a power source means more current moves through the circuit, and can destroy circuit elements by overheating. What about when you have a vaccuum cleaner intake flush against a floor, a room fan sitting directly against a wall, or a power drill trying to drill through something too hard?

I just purchased a 4 position cam switch to be used to operate a 3-speed blower motor. The motor is a 10 amp motor and has 3 wires that are used to control speed. The cam switch was rated at 660V 20 amps but when I received it, I noticed that it has AC-15 operational current rating (Ie) of 4/5 amps. If I am reading the label correctly. the 4/5 amps is related to 440v/220V (Ue). Other ratings are AC-3: 5.5A, AC2: 7.5A and AC-4: 1.5A. My questions are 1) Is it safe to use this switch with the motor I have 2) what is the difference between the 20 amp Ith ratting and the Ie operational ratings?
