Built with tin-plated aluminum construction, it is designed to split a primary power feed into multiple secondary circuits within panel assemblies, enclosures, or switchgear. The block accommodates a conductor range from 500 kcmil down to 10 AWG on the line side and supports up to 18 secondary openings, making it suitable for high-density wiring applications. Licensed electricians performing panel work and industrial control wiring will find this block suited to fixed junction and tap-off configurations where reliable, low-resistance termination is required.\u003c\/p\u003e\n\u003cp\u003eThis distribution block is used in residential and commercial panel assemblies, industrial control cabinets, and motor control centers where a single primary conductor must be distributed across multiple branch circuits. Its open-style design allows straightforward inspection and access to termination points during installation and maintenance. Typical applications include cable splicing, splitting primary power into secondary circuits, and establishing fixed junction tap-off points in box-to-box wiring configurations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSingle-pole open-style design rated 310 amps at 600 VAC for high-current distribution applications\u003c\/li\u003e\n  \u003cli\u003eTin-plated aluminum body supports 1,000-volt UL 1953 listing and resists corrosion at termination points\u003c\/li\u003e\n  \u003cli\u003eAccepts conductor range from 500 kcmil down to 10 AWG, accommodating a wide variety of wire sizes\u003c\/li\u003e\n  \u003cli\u003eUp to 18 secondary circuit openings in a box-to-box connection configuration\u003c\/li\u003e\n  \u003cli\u003eUL Listed (File E352417), CSA Certified (Class 6228 01), and RoHS Compliant\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an open-style power distribution block per UL 1953 for use in panel assemblies, industrial enclosures, and control cabinets requiring single-pole, high-ampacity distribution.
