This cable calculator is to be used as a guide only; the cable sizes are worked out using information given from your input, accurate values are essential to give you the correct cable size. The user is to ensure the type of cable is suited to environment and conditions the cable will be exposed to.
This cable calculator is set for Installation method C (Clipped Direct), for cable types BS5467 and BS6724 SWA (Steel wire armoured cable) and is based on the voltage drop selected at 230V single phase and 400V three phase.

The NYY cable range includes NYY-J and NYY-O cables. These are widely used European power and control cables designed for fixed wiring installation.
They can be safely deployed in most applications where mechanical stresses are not anticipated – indoors, outdoors, direct burial underground, in concrete, or submerged in water.
They are not suitable for installation in concrete which is shaken, vibrated or compressed.
When NYY cables are required to comply with the UK wiring regulations BS7671 for burial in the ground, they require installation in a conduit or duct to provide protection against mechanical damage.
