[RE-wrenches] Ilsco Insulated Tap Connectors

[Ray]

I pulled up the Ilsco site.  They are rated to 600 volts.  That voltage 
is AC and DC, unless it specifically says AC only.  We've used them for 
decades with DC.  Check your voltage rating for THHN cable: it does not 
say DC either.

Ilsco is also one of the few manufacturers to make flex cable rated 
connectors.  They have blue caps.  This is what we should be using when 
using higher strand count cables like Cobra X Flex.
