De energising means you are disconnecting a device from electricty source. Switch off the device, physically disconnect the device to de energise the circuit.

To de-energize an electrical circuit, remove the voltage source from the circuit. This is the purpose of the main disconnect, to isolate the circuit connected to the load side of the switch.

What fire fighting equipment do you use on an electrical fire?

A class "C" extinguisher (e.g. dry chemical or carbon dioxide) would be the choice for this one. However, if you can de-energize the electrical circuit, you would then be able to use water or another extinguishing medium on the fire. It might be a good idea to de-energize the circuit ASAP anyway, at least until you get the fire out and insure that re-energizing the circuit won't cause another problem. Fire does a nasty number on electrical equipment and wiring.

How do you de-energize a circuit?

To de-energize a circuit, the voltage has to be cut off at the source. This is usually done with a disconnect switch which is located just before the circuit's load. Turning off the breaker on a distribution panel will de-energize the circuit it is feeding. To make sure that the voltage can not be turned back on when work is being done on the circuit, the switch or breaker must have a lock off device to prevent the circuit from being turned on, except by the person that locked the circuit off.
