ABB TC300 – Frequently Asked Questions

1) What is the ABB TC300 raintight hub used for?
The TC300 is a raintight conduit hub that gives ABB Mini Mod and TDT switch enclosures a weatherproof conduit entry point. It seals the opening where conduit enters the enclosure so water stays out of the panel, which is what you need on outdoor and wet or damp location panel work.
2) Will an ABB raintight hub work on an outdoor load center, or only on Mini Mod and TDT enclosures?
ABB builds this raintight hub line to work across ABB load centers and panels that call for a raintight hub connection, with Mini Mod and TDT switch enclosures being the purpose-built application. Match the hub trade size to the knockout or hub opening on the enclosure you are fitting.
3) Is the ABB TC300 hub a 3 inch trade size?
The ABB raintight hub range includes a 3 inch diameter with a matching 3 inch base size, and the TC300 is the model designation for that configuration. Size the conduit run and the enclosure opening to 3 inch trade size before ordering.
4) Can a Square D rainproof hub be used in place of the ABB TC300 on a Mini Mod enclosure?
No. The ABB TC300 raintight conduit hub is built specifically for ABB Mini Mod and TDT switch enclosures and ABB load centers that take a raintight hub connection. The Square D Series A Meter Pak hub accessory is a rainproof hub matched to the Square D Series A Meter Pak, and the Square D B Series bolt-on hub is matched to the Square D B Series. Hub fit is tied to the enclosure opening and mounting pattern of its own product line, so pick the hub that belongs to the panel brand and series you are entering.
5) What is the Square D equivalent of the ABB raintight conduit hub for a meter pak installation?
For a Square D Series A Meter Pak, the rainproof hub accessory to specify is the Square D Series A Meter Pak hub. It serves the same purpose as the ABB TC300 raintight hub - a weatherproof conduit entry into the enclosure - but on the Square D Series A equipment rather than ABB Mini Mod and TDT switch enclosures. If the gear on the job is a Square D B Series instead, the B Series bolt-on rainproof hub is the matching part.
6) Can I use this hub on a wet location panel instead of a sealing locknut and bushing?
A raintight hub is the fitting intended for that job. A standard locknut and bushing does not seal the entry against driven rain; this hub is rated for outdoor enclosures and maintains the raintight seal at the point where conduit lands on the panel. Typical uses are outdoor panel installs, wet and damp location conduit entries, and panel retrofit work.
7) I am standardizing conduit entries across a portfolio of outdoor ABB panels. Is one hub part number enough?
No. The raintight hub comes in a range of trade sizes and the TC300 covers the 3 inch size with a 3 inch base. Survey the conduit sizes landing on each panel first, then order the matching hub size per entry; one part number only covers the openings at that size.
8) I am standardizing outdoor panel conduit entries across a property - do I need different hubs for different panel brands?
Yes. Raintight and rainproof hubs are brand and series specific. ABB Mini Mod and TDT switch enclosures take the ABB TC300 raintight hub, Square D Series A Meter Pak gear takes the Series A rainproof hub accessory, and Square D B Series gear takes the B Series bolt-on rainproof hub. A single hub part number will not cover a mixed fleet, so inventory by the panel line you actually have on site.
9) What is the difference between a bolt-on hub and the ABB TC300 raintight hub?
The Square D B Series hub is a bolt-on rainproof hub, meaning it fastens to the enclosure with bolts through the B Series pattern. The ABB TC300 is a raintight hub made to seal the conduit entry on ABB Mini Mod and TDT switch enclosures and ABB load centers. Both are intended to keep water out at the point where conduit enters the enclosure; they differ in the equipment line and attachment arrangement they are designed around, so the choice follows the panel already on the wall.
10) Do I get more than one hub per order, or is it sold individually?
Sold one each. If you are feeding several conduit entries on the same panel or running a multi-panel job, order a hub for every entry point rather than expecting a multi-pack.
