Application & Installation
Where it is used
- Neutral conductor support on 4-wire distribution systems
- Pole-top transformer secondary neutral connections
- Multi-grounded neutral (MGN) systems per NEC 250 (US distribution standard)
- Joint-use distribution where the neutral runs separately from the primary
- Telecom messenger ground bonding via a separate neutral bracket
Installation sequence
- Mark the pole 3–5 ft below the primary crossarm at the neutral elevation per drawing.
- Through-bore at 9/16 in (M12) or 11/16 in (M16) per bracket size.
- Install the bracket with a square washer on the back side.
- Thread the spool insulator onto the pre-tapped pin.
- Route the neutral conductor around the spool and tie or clamp per project standard.
Buyer’s Guide: Neutral Wire Bracket
1. When Do You Need a Neutral Wire Bracket?
A neutral wire bracket supports the neutral conductor on a 4-wire distribution pole, mounting below the primary crossarm. In US multi-grounded neutral (MGN) systems — the standard for utility distribution per NEC 250 — the neutral runs continuously along the pole line at a fixed elevation below the primary phases, with intermittent grounding to drive a desired earth-leakage path. The bracket carries a spool insulator (or porcelain bushing) that isolates the neutral from the pole while allowing it to be tied down at every pole.
Match the bracket size to the neutral conductor diameter: small for #6 to #2 AWG (typical for service-area distribution), medium for #2 to 1/0 (most-common rural), and large for 1/0 to 4/0 (heavy distribution or where the neutral also serves as a shield wire). The pre-tapped 5/8 inch pin thread accepts any ANSI-standard spool insulator — we supply matching porcelain spools on request.
2. How to Choose the Right Size
Pick by neutral conductor size.
- RAX-NWB-S — #6 to #2 AWG ACSR, urban distribution
- RAX-NWB-M — #2 to 1/0 AWG ACSR, rural distribution (most-ordered)
- RAX-NWB-L — 1/0 to 4/0 AWG ACSR, heavy distribution / shield wire
For conductors larger than 4/0 AWG or for non-MGN configurations (e.g., delta distribution without separate neutral), request a project-specific quote. 5–7 day tooling, 200-piece minimum.
