Terminal Blocks for Distribution Cabinet，Bridge‑type Neutral Earth Terminal Bar, Brass Copper Bus Bar

10Pcs/50Pcs/Pack Bulk Bridge‑type Neutral Earth Terminal Bar, Brass Copper Bus Bar 4‑16 Holes 20A 30A Zero Ground Terminal Block for Distribution Box size:6x9,8x12

4/6/8/10/12/14/16/22 Holes for Electrical Distribution Box

Bridge‑style zero‑earth terminal bar adopts thick brass conductor with acid‑washed anti‑oxidation surface. PA nylon flame‑retardant base rated UL94V‑02. Two main copper bar sizes:6×9mm(20A) and 8×12mm(30A), hole options from 4‑16 holes. Blue base for neutral bar, green base for earth ground bar. Galvanized iron screws for stable wire clamping. Widely used for wire splicing & bus connection inside household & industrial distribution cabinets, compatible with US 120V residential RCCB panel assembly.

Conductor & Surface Treatment

Main conductor: high‑thickness brass bar, acid‑washed surface treatment, anti‑oxidation, good electrical conductivity for large‑current load.

Screw: galvanized iron screw, stable clamping performance.

Insulation Base Feature

Base material: PA nylon, flame retardant grade UL94V‑02.

Blue insulating base for neutral zero bar; green insulating base for protective earth ground bar.

High impact resistance, safe insulation for cabinet installation.

Electrical & Mechanical Specs

  • 6×9 mm copper bar: Rated current 20A, max wire cross‑section ≤10mm²
  • 8×12 mm copper bar: Rated current 30A, max wire cross‑section ≤16mm²
  • Available hole quantity:4/6/8/10/12/14/16 holes
  • Type: Neutral Zero Bar / Earth Ground Bar

Application Scenarios

For domestic distribution box, industrial cabinet wire junction & busbar convergence.

Suitable for household wiring, match MCB, RCCB, US 120V residential electrical panel assembly.


FAQ

Q1: Difference between blue zero bar and green earth bar?

A: Blue base for neutral N wire; green base for PE protective ground wire, cannot be mixed under TN‑S wiring system.

Q2: What is max wire gauge supported?

A: 6×9 version fits up to 10mm² cable; 8×12 version fits up to 16mm² cable.

Q3: Can it install inside US 120V residential RCCB panel?

A: Yes, ideal for neutral and ground wire distribution inside distribution cabinet with 120V RCCB breaker.
