Consideration should be given to the size of the unit, the length of the cable run and the type of cable being used.

Only have installation work carried out by qualified technicians who will be able to calculate the correct cable size for each installation.

Wiring of the units must be in line with the latest edition of the IEE Wiring Regulations also known as BS 7671:2008.
