Hi Mac - Here's a list of NEC 230.46 compliant multitap connectors from NSI, maker of Polaris brand:
https://www.nsiindustries.com/line-side-skus/ Note that only the two-port variants are currently on their list, which is sort of a pain. We've been using the IT-350 which has dual-side wire entry, so we pass the primary conductor through the connector completely and strip the wire in the middle (roughly 1" middle-strip) to make the connection, then our tap conductor goes in the other port. If you go to the datasheet, you'll note they say "Connector sizes 350 to 750 MCM are suitable for use on the line side of the service equipment per NEC 230.46 requirements." That might be worth running by your utility if you need a variant with more than two ports. https://cdn.amplifi.pattern.com/fb4d416f-d614-48a7-b7de-a8f8615f501d I'm not aware of any insulation piercing connectors on the market meeting the NEC requirement, but I haven't been hunting that hard.
