[RE-wrenches] MC4s are listed for THWN, right?

[Corey Shalanski]

Chris's reminder is a good one—the 600V rating of most insulated
"multi-tap" connectors pretty much limits their use to residential systems.
I would also keep in mind that those connectors generally have a torque
spec. I've definitely seen examples of meltdowns caused by poor
terminations - either the compression screw isn't torqued properly or the
conductor isn't fully inserted. To help eliminate the latter case, we used
to favor the Burndy models (e.g., BIT4
<https://www.hubbell.com/burndy/en/Products/Power-Utilities/Connectors/Lugs-Terminals/Bolted/Vinyl-Insulated/BIT4/p/2021315>)
because they had a transparent case; I see that Polaris also now offers
transparent models (e.g., IT-4C
<http://www.nsiindustries.com/catalog/nsiproducts/polaris-mechanical-connectors/polaris-vision-tap/it-4c>
).
