You have to follow the lines. Could be blown fuse or any number of other things. Follow it back to the service.

Is 10 kva supply to 3 phase load is equal to 10kva supply to single phase load?
Yes of course!! 10 kva electrical power is 10 kva electrical power either it would be three phase or single phase. But other factors i.e. current, voltage changes accordingly. Actually this question is quit confusable. Because in 3phase system, if each phase gives 10kva power (single phase power = 10 kva) then 3 phase power will be 10 X 3 = 30 Kva If we go leteratualy towasrds the question, then the asnwer will be - No. becasue 10 kva supply to 3 phase load will be 3phase supply(i.e440V) & 10kva supply to single phase load will be single supply (i.e 250V).
Will a 3 phase motor work on grounded B phase?
If the motor is connected to an ungrounded delta supply service there will be no effect on the operation of the motor. If the motor is connected to a wye system supply service and the B phase grounds out, the motor's overload protection would take the motor off line from the electrical supply.
How do you convert 220 3phase ac to 125 vlt dc power or can you run dc motor on ac power just to test it for a minute or to without damaging the motor?
You can't. A three-phase motor works on a completely different principle from a d.c. motor (e.g. there's no electrical connection to the rotor). As well as this, with a d.c. supply, you will only be able to connect one phase of the field windings, and the resistance of that field winding will be low compared with its reactance, and may well burn out if you connected it to a d.c. supply.
Which electrical test requires the supply to be energized?
Testing of an electrical circuit for voltage requires the supply to be energized.
What is total voltage in 3phase supply when one of the phase becomes zero?
There is no 'total voltage' in a three-phase system. There are three line voltages and three phase voltages.
What is Reefer box?
A reefer box is an insulated shipping container designed to carry cargoes requiring temperature control. It is fitted with a refrigeration unit which is connected to the carrying ship's electrical power supply.
What point in an electrical circuit that is connected to the negative side of a power supply is called what?
battery
How do you use electricity in your life?
I read at night using a light bulb that is connected to an electrical supply.
How do you check the under voltage relay?
The way you check to see if an under voltage relay is wired properly is to disconnect the electrical supply. If the device that is connected to the load side of the relay does not start up or energize when the electrical supply is reconnected, then the relay is connected correctly.
Why battery is required in UPS?
In an uninterrupted power supply there has to be a source of power when the electrical utility is not there. The only supply that is available is a battery that is in or connected to the UPS.
What is a spur of a ring circuit?
this is a cable that is connected to a ring to supply electrical energy to one or more socket.
Where can I find the best true refrigeration for my home?
True-brand refrigerators are designed for commercial use, such as restaurants. If you really need this type of refrigeration in your home you will have to visit a restaurant supply store. Also, before you buy be sure your electrical system is compatible.
How much tons of refrigeration can supply a 10 square meter room?
1/2 ton of refrigeration

What is the primary objective of the Philippine electrical code?
As with every electrical code around the world, the primary objective is the safe installation of electrical equipment that is connected to the electrical grid. Overall the objective is keeping everyone and everything safe in conjunction with the use of an electrical supply source.

How could you find the purpose of a parallel circuit?
For an electrical load, such as a lamp, heater or motor, to operate at its rated power, it must be subject to its rated voltage which always corresponds to the supply voltage. For this to happen, individual loads must be connected in parallel with the supply and with each other. So all the electrical loads in your home, in your car, etc., are ALL connected in parallel.
