Yes that's good advice. Thanks. However, this work is just a small part of a larger job that will be bid so I wanted to specify a particular kit. Thanks again.
This is a USA application.
I need to terminate a set of 5kV shielded single conductor cables (500kcmil) at lugs in an MV switch. Can anyone recommend a particular manufacturer's kit. Or, are there any in particular that you do not recommend. I'm aware of Raychem and 3M but I don't know who's kit...

DeltaV guidelines recommend that you isolate the signal ground from AC ground in control enclosures, etc., and only connect them together at the grounding electrode by using separate grounding electrode conductors.
Having said that, the conductor sizes that DeltaV calls out for their signal...
I've never seen a new 4X enclosure (offered for sale by and enclosure manufacturer) that had vents in it. Having said that, I have seen many NEMA 4X or 4 enclosures that have been modified with vents after purchasing. Can it still be considered a NEMA 4X enclosure once it's ventilated? Probably...
Soft drawn copper (or annealed copper) has a lower breaking strength than hard drawn copper, however, it does have lower resistivity. Use the soft drawn for your ground wire. Use hard drawn for long overhead lines that require higher strength. You probably won't know the difference in the field...
Yeah, what amptramp said. Unless of course, you have time and money to burn. It's no disgrace to get appropriate help but it's just plain dumb to forge ahead hoping for the best. It always seems that there is never enough time and money to do it right the first time, but there is always time and...
I have had dozens of older MCC buckets retrofitted with new Advantage starter buckets on older F10 and 9800 C-H MCCs. I can only recall one problem that was similar to yours. We had a size 2 starter that would inexplicable just turn off. As if the starter coil circuit was opened. C-H replaced...
