Ark Detection Device
An ark detection device was a component that used to be used on the fuse board of houses before RCD’s were commonly used. An ark detection device would register if an un-earthed electrical circuit was arking and would automatically cut off the electrical supply.
In Heat Mat’s opinion all un-earthed mains voltage underfloor heating should be protected by an ark detection device for safety reasons.
Heat Mat do not supply any un-earthed underfloor heating products.
