4160v connections

[patriot]

I'm installing a 4160v transferswitch to an existing duel fed service. I need to extend the feeder wires to tie into the transferswitch. I'm using stess cones on all termanations and was thinking about extending the wires by using high pressure crimps and bolting them together. Does anyone see a problem with doing this?

If you are not going to replace the cables (I would recommend replacing them) you should use MV splice kits, I would also have the cables tested before putting them back in service.

I agree with Roger, honestly I you have to ask, you may want to get a certified MV cable splicer involved. They should be tested by VLF, PD, or TD method prior to energizing.

And I agree with Zog, you should probably sub this out to the experts in this field.

Doing this will not insure the semi conducting jacket and shield keep their required integrity.
As the others said a certified MV contractor is well worth the money, as you are dealing with some very expensive cables and equipment.

Thanks for the replies. Making up the terminations won't be a problem for me. I'm not certified but i've made up probably 150 or so terminations. I've also used isolated buss bars in a stainless junction box to make a juntion between a motor controller and a motor(all 4160). But I really dont like the idea of bolting two wires together to extend them. I'm probably just going to pull new wire to the transferswitch.
