Eaton INK400 – Frequently Asked Questions

1) What does the Eaton INK400 neutral kit actually do in an enclosed breaker installation?
The INK400 is a neutral kit that adds a neutral terminal assembly inside an enclosed circuit breaker, so the incoming and outgoing neutral conductors have a proper landing point. It is rated 400A and is set up as an insulated and groundable neutral, meaning it can be kept isolated from the enclosure or bonded to it depending on whether the installation is service equipment or a downstream feeder.
2) Will the Eaton INK400 neutral kit fit in my enclosure?
The kit measures 6 x 7.5 x 3.75 inches, so you need that much clear space in the gutter area of the enclosed breaker before you commit. Measure the free space beside and below the breaker, not the overall box size, since the breaker and its conductors already occupy part of the interior.
3) Can I use the INK400 with a three-pole breaker, or is it only for single-pole?
It is configured for use with (3) single-pole breakers, which is the arrangement it is listed for. If your enclosed breaker is a single three-pole device, this is not the kit that matches that configuration.
4) What is the difference between an insulated neutral and a groundable one, and which way do I install this kit?
An insulated neutral sits on standoffs and stays separated from the metal enclosure, which is what you want on a feeder or subpanel where neutral and ground must remain separate. Groundable means the same bar can be bonded to the enclosure, which is required where the enclosed breaker serves as service equipment. The INK400 is built to do either, so the install decision is yours based on where the breaker sits in the distribution system.
5) Is the Eaton INK400 neutral kit UL Listed for commercial work?
Yes, the INK400 carries a UL Listing, which is what inspectors and institutional spec writers look for on an accessory installed inside listed enclosed breaker equipment. Field-added neutral bars that are not part of a listed kit are a common source of inspection trouble; this one is covered.
6) Does a 400A neutral kit have to match the breaker's amp rating?
The INK400 is rated 400A, so it suits an enclosed breaker application at or below 400 amps. Using it on a larger frame would put the neutral path below the rating of the circuit, so match or exceed the circuit's neutral requirement.
7) Can I add this neutral kit to an enclosed breaker that is already installed?
Yes. The INK400 is an accessory kit intended for field installation in enclosed circuit breaker assemblies, which covers retrofit and upgrade work on existing equipment as well as new builds. The limiting factors are the 6 x 7.5 x 3.75 inch space it occupies and that the breaker arrangement is (3) single-pole devices.
8) What is the Eaton part number for this 400A neutral kit?
Order it as Eaton INK400. That is the catalog number for the 400A insulated and groundable neutral kit used with enclosed circuit breakers.
