It is designed to split a primary power feed into multiple secondary circuits within an electrical enclosure or panel. The block features tin-plated copper construction for reliable conductivity and corrosion resistance. It accepts one conductor on the line side and up to 10 conductors on the load side, making it well suited for high-current distribution applications in commercial and industrial electrical systems. Licensed electricians install this component during panel builds, service upgrades, and circuit expansion projects.\u003c\/p\u003e\u003cp\u003eThe MPDB66591 is applied in fixed junction tap-off points, cable splicing configurations, and primary-to-secondary power splitting scenarios. Its box-to-box connection style allows direct mounting within standard electrical enclosures. The line-side conductor range accommodates wire sizes down to 2\/0 AWG, while the load side accepts conductors down to 6 AWG, providing flexibility across a range of circuit sizes. This block is suited for commercial panel assemblies, industrial control cabinets, and similar fixed-wiring installations where a centralized distribution point is required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSingle-pole, open-style design accepts 1 line-side conductor and up to 10 load-side conductors\u003c\/li\u003e\n\u003cli\u003eTin-plated copper construction for low resistance and long-term durability\u003c\/li\u003e\n\u003cli\u003e175 amp current rating at 600 volts AC for heavy-duty distribution applications\u003c\/li\u003e\n\u003cli\u003eBox-to-box connection style for direct enclosure mounting\u003c\/li\u003e\n\u003cli\u003eUL Listed (File E352417), CSA Certified (Class 6228 01), and RoHS Compliant\u003c\/li\u003e\n\u003cli\u003eConductor range: line side 2\/0 AWG and larger, load side 6 AWG and larger\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style open power distribution block for use in fixed electrical enclosures and panel assemblies where UL 1953-listed components are required.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize and lock out the panel before installing or servicing this block. Confirm conductor torque requirements from the enclosure manufacturer documentation before terminating wires.
