Regulation 421.1.201 in Amendment 3 to the wiring regulations is not just about non combustible enclosures for consumer units, this new regulation requires non combustible enclosures on similar switchgear assemblies too.
“Similar switchgear assemblies” includes switchgear that is used for the same fundamental purpose as consumer units i.e. circuit protection applications within domestic household premises.
This is why Wylex have introduced several additions to their Amendment 3 range.
As well as the NM range of consumer units there’s the range of Meter Cabinet Consumer Units (previously known as Skeleton Units) in full non combustible all metal enclosures. These bespoke units are designed for use in high rise, and similar applications where the electricity meter is housed within a cabinet outside the dwelling and the consumer unit is located in the same enclosure in the space above the meter.
In addition there is a brand new range of Domestic Switch Fuse Units in all metal non combustible enclosures. These products are used wherever large buildings are being converted into several apartments. These are ideally suited for sub main circuit protection applications in 60A 80A & 100A ratings.
To further enhance the fire safety standards that are intended by regulation 421.1.201 Wylex, has introduced a range of accessories including intumescants, flame retardant grommets, non combustible blanks & mains tails glands
All Wylex domestic circuit protection units meet the requirements of the relevant product standards (BS EN 61439) and the latest requirements of BS7671 Wiring Regulations including Amendment 3.
