What are the dangers of mains electricity?

The main hazards of working with electricity are:

  • electric shock and burns from contact with live parts.
  • injury from exposure to arcing, fire from faulty electrical equipment or installations.

Is mains electricity alternating or direct?

The voltage from the mains supply is alternating. This produces an alternating current ( ) in circuits. This means that the current in a circuit using a mains supply continually changes direction backwards and forwards in a circuit.
