NSIIndustries Polaris Black IPL3/0-3B Insulated Multi-tap Connector,3-Port Single-Sided Entry for 3/0-6 AWG Wire Range,Dry Locations, 2.63-inch length,Hex size 5/16-inch

Q: Will this work for a 6/3 gauge romex wire with ground?

Not sure to be honest. I used it for a 12/3 type wire. It does screw down on the wire to hold it in place - so yours should work.

Q: Does this connector really cost 25.87 for a single, 4 port connector?

.....and its insulated and you can mix metals. I had aluminum in from the electric company and connected copper wires to it. This was for ground and common. Usually the 3 port or splicing (2 port) works for most applications. My hybrid solar inverter output was going to the house (output 1), the hottub and a/c units (output 2) and the guest house (output 3) so needed 4 ports. Morris has some less expensive ones. I've used both and morris is often a better deal.

Q: would like to know what size the openings are. Would they work for 4/0 cable which is nearly a 1/2 inch in dianeter? THanks for your time

No it will not work with 4/0 it’s #4 max

Q: I’m wondering if these terminals are connected internally or are they good to use when splicing together AWG 3 wire?

they are connected it is best to just put 1 conductor in each receiver then when you tighten the set screw it will remain a solid connection with no chance of heating and becoming loose.
