Ferraz Shawmut MPDB68310 Power Distribution Block 760A

Product Description

The FERRAZ SHAWMUT MPDB68310 is an open-style power distribution block rated for 760 amps and 1000 volts, built from tin-plated copper for reliable conductivity and corrosion resistance. Part of the MPDB Series, it carries a UL 1953 listing and is designed for box-to-box wiring configurations. It features an Adder 2 design with 4 openings, accepting line-side wire ranges of 500 to No. 4 AWG and load-side wire ranges of 4/0 to No. 10 AWG. Electricians install this block in panelboards, switchboards, and industrial enclosures where branching high-current circuits to multiple load conductors is required.

This distribution block suits commercial and industrial electrical installations where a single high-ampacity feed must be split across multiple circuit conductors within an enclosure. The box-to-box mounting configuration allows direct integration between adjacent enclosures or wireway sections, simplifying high-density panel layouts. The 4-opening Adder 2 configuration provides additional circuit positions when used alongside a base block, making it a practical solution for expanding existing distribution assemblies in panel upgrades or new construction.

Key Features

• UL 1953 listed open-style power distribution block for code-compliant installations
• 760A continuous current rating at 1000 volts AC
• Tin-plated copper construction resists oxidation and maintains low contact resistance
• Adder 2 configuration with 4 openings expands capacity of existing base block assemblies
• Wide wire range: line side 500 to No. 4 AWG, load side 4/0 to No. 10 AWG
• Box-to-box design integrates directly between enclosures or wireway sections

Compatibility

Designed as an OEM-style Adder 2 block for use with compatible MPDB Series base power distribution blocks in UL 1953-compliant open-style applications.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize and lockout/tagout all circuits before handling or terminating conductors at the block. Verify that conductor sizes and insulation ratings match the block wire range and system voltage before terminating. Do not exceed the 760A continuous rating or the specified wire range on either the line or load side.
