If you want to check a circuit is dead (not live), you should always use the three point method. First check a known live circuit, then check the dead...
While there are a vast array of cable insulation materials, these are often divided into two general types; Thermoplastic or Thermosetting. For example...
The other day I was talking to a colleague who is a building services consultant. Despite regularly specifying dry-type/cast resin transformers he was...
