B-LINE TA350DA – Frequently Asked Questions
1) What wire size does the B-Line TA350DA terminal accept?
The TA350DA is a standard pressure terminal rated for 250 to 500 kcmil conductors, copper or aluminum. That covers the usual feeder range on a 350A breaker, and the dual Cu/Al rating means you don't need a separate lug for aluminum feeders. Anything smaller than 250 kcmil or larger than 500 kcmil needs a different terminal.
2) Will the TA350DA fit an Eaton Series C molded case breaker?
Yes. The TA350DA is an Eaton Series C molded case circuit breaker terminal, sold as a factory accessory for that line. It is not a universal lug, so it should be applied to Series C frames at the 350A rating rather than swapped onto another manufacturer's breaker.
3) Does one TA350DA cover a three pole breaker, or do I need three?
Each TA350DA is a single terminal, ordered one per pole. A three pole Series C breaker needs three at the line end and three at the load end if both ends are being terminated, so count your poles before ordering.
4) What is a standard pressure terminal, and when would I use one instead of a compression lug?
A standard pressure terminal is a mechanical set screw lug: you strip the conductor, land it in the barrel, and torque the screw. No crimp tool, no die set, and the conductor can be re-terminated in the field. Compression lugs need a hydraulic crimper and the matched die, but give you a permanent factory-style termination. For field work on a 350A Series C breaker where a maintenance electrician may need to pull and re-land the feeder, the pressure terminal is the practical choice.
5) Can I land two smaller conductors in one TA350DA instead of a single 500 kcmil?
No. The TA350DA is a single conductor terminal rated for one 250 to 500 kcmil copper or aluminum wire. Parallel feeder runs need a terminal built for two barrels per pole, not two conductors forced into one opening.
