According to the Electricity at Work Regulations, what must be done to circuits on which engineers work?

• Circuits should be made dead.

• Circuits should be left live.

• Circuits should be partially live.

• Circuits should be disconnected.

When is live work on circuits permitted according to the regulations?

• When it is not practical for the circuit to be dead.

• When it is convenient for the engineer.

• When the circuit is new.

• When the circuit is old.

What does the rule about testing imply regarding working on live circuits?

• Engineers cannot work on live circuits just because it is inconvenient to turn off the supply.

• Engineers can work on live circuits if they are in a hurry.

• Engineers can work on live circuits if they have permission.

• Engineers can work on live circuits if they are experienced.
