Tails size

Former Community Member
Former Community Member
Hello hope everyone has managed to keep safe this far. 


I need to install a TPN isolator from the cutout so if needed for future maintenance we can isolate panel board. 


​​​​​My question is what size tails would I need the isolator will be within 2m of the panel board looking at table 4D1A column 9 looks about right which leads to 70mm cable how easy are these to handle and terminate also are there any alternative suggestions? 


This will be my first time playing with tails this size ?


Thanks in advance Ts.

    That's a good point you make about the sustained current draw and heat generated John. 


    Just like to thank everyone for their replies, the client has now decided to stick with the original 100A TPN supply ?.
