Bussmann 16400 – Frequently Asked Questions

1) What size feeder can a Bussmann 16400 power distribution block handle?
The Bussmann 16400 barrier block is rated 1520A at 600 Vac and 600 Vdc, so it handles high-amperage feeder and service splices rather than branch-circuit taps. Because it carries the same 600V rating on both AC and DC, it works in DC bus and battery distribution as well as standard AC panel work.
2) Does the Bussmann 16400 distribution block meet the SCCR my panel needs?
The 16400 carries an SCCR of 10 kAIC. If the available fault current at the point of installation exceeds 10 kA, or the panel assembly is being labeled for a higher short circuit current rating, this block will be the limiting component and you need a higher-rated block. On systems where the upstream overcurrent device holds let-through within 10 kA, it is fine.
3) Will a Bussmann 16400 block fit in my enclosure?
Plan on 4 inches by 3.32 inches of footprint for the 16400, plus whatever bend radius your conductors need coming into the connectors. At 2.1 lb it mounts to a panel back-plate or subpanel without special support.
4) Can I land copper conductors in a Bussmann 16400, or is it aluminum only?
Connectors on the 16400 are tin-plated aluminum. Tin plating is what lets an aluminum-body connector take copper without the dissimilar-metal corrosion you would get on bare aluminum, and it also resists oxidation on the aluminum side. Torque the lugs to the values marked on the block and re-torque per your commissioning procedure.
5) What is the difference between a barrier power distribution block and an open one?
A barrier block puts molded insulating walls between each phase, so the poles are physically separated at the termination points. That matters when the block sits in a crowded panel, when conductors are being landed live-adjacent, or when an inspector wants clear phase separation. An open-style block leaves the poles exposed and generally needs a separate cover to get the same protection. The 16400 is the barrier type, with a molded thermoplastic base doing the insulating.
6) Is the Bussmann 16400 power distribution block suitable for a motor control center or switchgear build?
Yes, that is the class of work it is built for. Panel builders use the 16400 for splicing and distributing high-amperage feeders inside industrial distribution panels, MCCs, switchgear, and panelboard splice points. The deciding factor is not the application but the fault current: the block's 10 kAIC SCCR has to be at or above the available fault current where the assembly is installed.
7) What is the correct part number to order for the Bussmann 1520A barrier distribution block?
Order it as Bussmann 16400. That is the manufacturer part number and the only model on the line, so there is no separate ampacity, pole, or finish suffix to specify. The block ships black.
8) Can a Bussmann 16400 be used on a 480V three-phase feeder?
Yes. The 16400 is rated 600 Vac, which covers 480Y/277 and 480 delta systems as well as 208/240 work. The same block is rated 600 Vdc, so it is not limited to AC service.
