Three-phase power

Installing or extending a three-phase supply, used where a single-phase supply cannot carry the load, typically in workshops and commercial units. Three-phase power work is carried out by electricians across the national directory, with businesses concentrated in London and further representation in Eastleigh, Sheffield, Bristol and Colchester.

Why people have it done

  • Loads a single-phase supply cannot carry are supported, which is what workshop machinery usually asks for.
  • Demand is spread across three phases instead of drawn through one.
