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.

I have heard AC DC no difference. However, I have experienced failure
of these connectors via insulation softening in J boxes on the roof.
The plastic is not thermal set and it will distort if pressured
against the side of the box. This has never been a problem for
interior wiring only in the solar case outside.

Aloha Wrenches,
Does anyone know if Ilsco Insulated Tap Connectors at DC rated?
I looked on their cut sheet, and even called the Cincinnati and I
was not able to confirm this?
Does anybody know this, or have a better connector to use?
Mahalo in advance,
