[RE-wrenches] Wago Connectors (221 series)

[Jason Szumlanski]

In another thread these connectors were discussed recently. There was a
question regarding the suitability for DC circuits. I don't think we came
up with any answers or consensus on that. I see the connectors are UL
listed to the 486C standard. I can't determine whether that is applicable
to AC and DC circuits. Does anyone know?

I have only used these on AC circuits and they have been very effective.
Now I'm curious whether they can be used on DC circuits up to 600 volts.

While on the subject, I noticed they are UL 467 listed for grounding and
bonding. That's helpful where you have EGC splices for conductors up to #10
AWG inside junction boxes.
