nVent CADDY TMGBA Tin Plated Copper Telecom Main Grounding Busbar

The nVent CADDY TMGBA Telecom Main Grounding Busbar is a Tin Plated Copper Main Grounding Busbar (MGB) engineered to provide a centralized, low-impedance grounding point for telecommunications and data equipment racks, frames, and equipment rooms. This busbar family is available in 12-Inch (36-Hole) and 18-Inch (23-Hole) configurations, giving installers a size and pair-hole count suited to the scope of the equipment room or rack lineup being grounded. The Tin Plated Copper construction delivers excellent conductivity and corrosion resistance for long-term, code-compliant grounding performance in professional telecommunications installations, helping installers consolidate bonding connections at a single, accessible busbar rather than running individual ground conductors to scattered termination locations throughout the equipment room. Whether outfitting a compact telecom closet or a larger central office frame lineup, the TMGBA busbar family gives installers a dependable, centralized bonding point built to support consistent grounding practices across the installation.

Key Features

  • Size Options: Available in 12-Inch (36-Hole) and 18-Inch (23-Hole) configurations to match the grounding scope of the rack, frame, or equipment room.
  • Durable Construction: Tin Plated Copper construction resists corrosion while maintaining high conductivity for a dependable ground path over the life of the installation.
  • Multiple Pair-Hole Terminations: Both size options provide numerous pair-holes so multiple ground conductors can terminate at a single, centralized busbar rather than separate ad-hoc points.
  • Main Grounding Busbar Function: Serves as the primary bonding point (MGB) for telecommunications grounding and bonding systems in a rack or equipment room.
  • Telecom-Grade Finish: Tin plating over the copper busbar body helps resist oxidation at conductor termination points over time.
  • Space-Conscious Footprint: Compact busbar profiles across both size options fit into telecom cabinets and equipment bays without consuming excess rack space.

nVent CADDY TMGBA12L15PT – Frequently Asked Questions

1) What is the difference between the nVent CADDY TMGBA 12-inch and 18-inch grounding busbars?
Two sizes are offered: the TMGBA12L15PT is the 12-inch bar with 36 holes, and the TMGBA18L23PT is the 18-inch bar with 23 holes. Both are tin plated copper main grounding busbars. Pick the one whose hole count covers every bonding conductor you expect to land now plus spares, rather than sizing purely on bar length.
2) Is the TMGBA a main grounding busbar (MGB) or a secondary bonding busbar?
It is a Main Grounding Busbar. The TMGBA is intended as the primary bonding point for a telecom grounding and bonding system in a rack lineup or equipment room, with individual ground conductors brought back to it rather than terminated at scattered points. If you need a smaller downstream bar at each rack row, that is a secondary bonding busbar, a different part.
3) How many ground conductors can I land on the nVent CADDY TMGBA busbar?
The 12-inch version provides 36 holes and the 18-inch version provides 23 holes, drilled in pairs so two-hole lugs can be bolted down. That hole count is the practical limit on how many bonding conductors terminate at the bar, so count your racks, cable trays, cabinets, and structural steel bonds before choosing a size.
4) Why use a tin plated copper busbar instead of bare copper for telecom grounding?
The TMGBA bar is copper with a tin plating, so you get copper conductivity with a plated surface that resists oxidation right where ground conductors clamp down. Bare copper oxidizes at the termination points over time, which is what raises resistance at the lugs in an equipment room that stays in service for decades.
5) Can I use this busbar in a telecom closet, or is it only for central office frame rooms?
Both. The TMGBA family is used in telecom equipment rooms, data center rack and frame grounding, central office grounding systems, MDF and IDF closets, and retrofit grounding upgrades. The 12-inch bar suits a compact closet; the 18-inch bar is the one to reach for on a larger frame lineup.
6) Does the TMGBA grounding busbar come with insulators and mounting brackets?
The TMGBA is supplied as the tin plated copper bar itself. A main grounding busbar is normally stood off the wall or rack on insulators, so plan on standoff insulators, wall mounting hardware, and two-hole compression lugs for each conductor as separate line items on the order.
7) What part number do I order for a 12-inch nVent CADDY telecom grounding busbar?
TMGBA12L15PT is the 12-inch, 36-hole tin plated copper bar. The 18-inch, 23-hole version is TMGBA18L23PT. Size is the only choice to make on this family.
