hi there i went to a job the other day,and found there was no incoming earth on the main supply cable,i was told by the supply company,to install an earth electrode,the incoming supply system is a t.n.s.type,would this electrode then make this a t.t. system,if so would i have to upgrade the exsisting consumer unit,with an insulated type with r.c.b.o. devices,with a standard 100 amp main-switch.?:nonod:
