Patent ID: 7688564

Claim:
A power distribution system for use in distributing electrical power, said distribution system comprising: a source of incoming electrical power comprising at least a first electrical circuit; a cable or conduit assembly having at least a first junction block coupled to interconnecting cables, where at least one of said interconnecting cables is electrically coupled, directly or indirectly, to said incoming power circuit; electrical receptacle means releasably and electrically connectable to said first junction block; a second junction block electrically connected to said first junction block and located upstream of said first junction block, relative to said incoming power circuit; surge protection means releasably and electrically connectable to said second junction block, said surge protection means being pluggable into said second junction block and having means for protecting said first junction block and said electrical receptacle means from excessive voltages which may be applied to said first electrical circuit while said first junction block locates downstream of said second junction block; and said surge protection means is pluggable into, and connectable to, said first junction block, in a manner interchangeable with said electrical receptacle means being connected to said first junction block.
