how do i wire a emersion heater to a fused spur?

Make sure supply is isolated first !!!
The Fused spur should idealy be a switched fused spur with a neon indicator !! The terminals in the fused spur will be labeled " Load L & N" using 1.5 MM heat resisting flexible 3 core cable. Brown to L Blue to N and grean and yellow to the earth connector in the spur. Inside the imersion heater The blue wire goes to the N terminal The green and yellow goes to the Centre fixing bolt secured under the bottom nut and clamp washer. The brown goes to the L terminal of the internal thermostat. There should be a link wire allready fitted between the Output terminal of the thermostat and the L connection of the heating element.
