What is the history to busbar trunking?
Busbar trunking has been in the UK for more than 50 years. It has progressed from derivations of busbar chambers with heavy metal gauge, metal enclosures with bolt-on covers and clamp connections for tap-offs to totally enclosed sheet steel or aluminium casings with either copper or aluminium conductors and plug-in, tap-off outlets, which are fully shuttered and finger protected for increased safety.
