Cable Spacing Guide

Use the table below to determine your requirements.

To calculate cable spacing, use the following formula:  Area (m2) ÷ Cable Length  X 1000 = cable spacing (mm)

For greater areas individual cable lengths can be joined in any configuration and connected in parallel.

A contactor can be used where a single thermostat is required to control a total area of underfloor heating exceeding a 13amp fused spur supply. Please contact us for detailed wiring instructions
