How to Wire a Fused Spur

Save

A fused spur provides protection for a branch wire off a main circuit. This branch is commonly a lower amperage circuit and thus requires its own fuse to protect the lower-gauge wires. This arrangement is commonly used in the United Kingdom and may not meet local building codes in North America. Consult with your municipal building authority before installing a fused spur in your home.

Things You'll Need

  • Noncontact voltage detector
  • Wire strippers
  • Screwdriver
  • Turn off the power for the circuit you are working on at the home's electrical distribution panel. Confirm the power is off by touching a noncontact voltage detector to the wire's insulation.

  • Strip 3/8 inch of insulation off the three conductors in the supply and the branch wire with wire strippers.

  • Loosen the ground screw in the back of the electrical box and wrap both green or bare wires around this screw. Tighten the terminal down with a screwdriver.

  • Wrap the black supply wire around the fused spur's supply live (L IN) terminal and tighten it down.

  • Wrap the white neutral supply wire around the fused spur's supply neutral (N IN) terminal and tighten it down.

  • Wrap the black branch wire around the fused spur's live out (L OUT) terminal and tighten it down.

  • Wrap the white branch wire around the fused spur's neutral out (N OUT) terminal and tighten it down.

Tips & Warnings

  • Working around electricity has the potential to be very dangerous. If you don't understand safe electrical practices, hire an electrician to do the work.
