B-LINE SBTMGB20K – Frequently Asked Questions

1) Is the B-Line SBTMGB20K a complete telecommunications main grounding bar kit, or do I need to buy brackets separately?
The SBTMGB20K ships as a kit. It includes the ground bar assembly, hex nuts and lock washers, and the copper bar comes with SS4 wall brackets for standoff mounting. You still supply your own wall anchors and the bonding conductors and lugs for the terminations.
2) How much wall space do I need for a 20 inch telecom main grounding bar?
Plan on a 20 inch wide footprint. The assembly measures 20 inches wide, 6.63 inches high, and 3.13 inches in length/depth, so allow clearance on the backboard for the bracket standoff and for conductors routing to the bar from both sides.
3) Is the B-Line SBTMGB20K ground bar UL Listed?
Yes, the SBTMGB20K telecommunications main grounding bar is UL Listed, which is what most spec writers and inspectors look for on a TMGB in a telecom or equipment room.
4) Is this a TMGB or a TGB? Which one goes in the main entrance room?
This is a telecommunications main grounding bar, the TMGB. One TMGB is installed per building, normally in the entrance facility or main equipment room, and it is bonded to the building service ground. Secondary telecom rooms on other floors get a smaller telecommunications grounding bar (TGB) that bonds back to this bar through the bonding backbone.
5) Is the bar solid copper or plated steel?
Solid copper. The bar itself is copper, which is what keeps resistance low across the terminations and lets you land compression lugs directly on the bar without a dissimilar metal issue at the connection.
6) What part number do I order for the Eaton B-Line 20 inch telecom main grounding bar kit?
Order B-Line (Eaton) SBTMGB20K. That is the single catalog number for the 20 inch copper TMGB kit with SS4 wall brackets and mounting hardware.
7) How heavy is the SBTMGB20K, and can one person mount it?
The assembly weighs 10.1 lb, so one electrician can handle it, but at 20 inches wide it is easier to set with a second person holding the level while the SS4 brackets are anchored. Anchor into plywood backboard or solid blocking rather than bare drywall.
8) Where is this ground bar meant to be used?
It is intended for low voltage system grounding inside a room, typically a telecom or equipment room where data, security, and other low voltage systems are bonded to a single point before tying back to the building ground.
