We carry out commercial up-grades and installations.
In this installation in Hertfordshire, there were 5 fuse boards and 3 local electrical meters. After re-wiring the complete office, we removed the old installation and installed a new consumer unit using a split board so that if anything did trip, only that circuit would trip. This would greatly reduce the amount of nuisance tripping - especially when circuits need to definetly need to avoid being tripped by other circuits.
In most cases we will use the fuse board or consumer unit that we feel is best for the job with the provision of expansion. In most cases Contactum's metal clad units are very suitable for most applications.
