Morris 91156 Copper Neutral/Ground Bar, 13-Circuit, #14-#4 AWG, Mount 3 & 13

Product Overview

The Morris 91156 is a machined copper neutral/ground bar configured for 13 circuits (15 total holes) and designed for copper conductors only. It accepts a range of conductor sizes from #14 AWG through #4 AWG and is rated for 600V.

Intended for termination and commoning of grounded (neutral) or grounding (equipment-ground) conductors in panelboards, load centers, meter sockets and enclosures. The bar includes mounting hole positions at 3 and 13 and a length of 4.74".

Key Features

• Machined copper construction — for copper conductors only
• 13-circuit layout with 15 total holes
• Range-taking: accepts #14 through #4 AWG conductors
• 600V rated
• Mounting hole positions: 3 & 13; overall length 4.74"

What this part is used for

The Morris 91156 is a neutral/ground bar used to terminate and common multiple grounded (neutral) or grounding (equipment-ground) conductors inside electrical enclosures. Typical installs include panelboards, load centers, meter sockets and other enclosures where consolidated copper terminations are required.

• Provides centralized termination for up to 13 circuits (15 total holes).
• Supports both neutral and equipment-ground conductors where a dedicated copper bar is specified.

Electrical ratings and conductor compatibility

Use this bar only with copper conductors. It is range-taking and accepts conductors from #14 AWG up to #4 AWG and is rated for 600V.

• Wire range: #14–#4 AWG
• Voltage rating: 600V
• Conductor material: copper only

Mounting and basic installation notes

Mount the bar to the enclosure at the provided mounting hole positions (labeled 3 & 13). Land one conductor per port and secure each conductor using the individual set-screw terminations.

• Mounting hole positions: 3 & 13
• Terminate one conductor per hole and tighten set screws to secure conductors

Physical dimensions and material

The bar is machined from copper and measures 4.74" in length. The copper construction and specified conductor compatibility mean it is intended for direct copper-to-copper terminations.

• Material: copper
• Length: 4.74"
• Circuits: 13 (15 total holes)

Before You Order

Confirm the model number and quantity required before ordering. Verify that copper-only conductor compatibility, the #14–#4 AWG wire range, and the bar's 4.74" length meet your installation and code requirements.

• This bar is for copper conductors only — do not use with aluminum or bi-metallic terminations unless explicitly permitted by a separate connector or listed assembly.
• Confirm mounting hole positions (3 & 13) and overall length for fit within your enclosure.
