There are thousands of electrical fires each year within domestic, commercial and industrial premises-many of which happen due to wiring faults and overloads. Existing protective devices, such as MCBs and RCDs, do not prevent this problem from occurring as they cannot sense the excessive heat associated with such faults.
In response to increasing concerns regarding fire safety, Amendment 3 to BS 7671:2008 (IET Wiring Regulations) makes a fundamental change to the selection of consumer units in domestic premises. The principle behind this change is to contain any fire within the non-combustible enclosure of the consumer unit, but it does nothing to stop the fire starting in the first place.
A solution to this problem was not available-until now. For more information about our unique fire safety product, please click the image opposite to download our brochure. Please also see below for links to installation, safety and conformity documents.
It has been proven that a plastic consumer unit fitted with a Thermarestor® system offers a safer solution to that required by Regulation 421.1.201 simply because it is designed to prevent the fire happening in the first place.
