Marathon Special Products 1512STD Barrier Terminal Block

Product Description

The MARATHON SPECIAL PRODUCTS 1512STD is a 12-position, 2-row barrier terminal block designed for panel mount installations in industrial and commercial electrical systems. Rated at 30 amps at 600 volts AC/DC, it accepts 10-22 AWG solid or stranded copper conductors and features a 15.88 mm pitch spacing between positions. The block is built for unprepared wire terminations and is torqued to 20 inch-pounds per terminal. Licensed electricians and panel builders use this block to organize and secure multiple circuit connections in a single, compact assembly.

This barrier terminal block suits panel wiring in commercial control panels, industrial machinery, and electrical distribution enclosures. The 2-row, 12-position layout consolidates multiple circuit connections into one strip, reducing wiring time and improving organization inside the panel. It is a direct screw-type termination block intended for copper wire only. Installations follow NEC guidelines for terminal block wiring and enclosure grounding practices.

Installation Notes

Installation should be performed by a licensed electrician in accordance with applicable NEC requirements. De-energize the panel completely before installing or servicing the terminal block. Use copper conductors only within the 10-22 AWG range and apply terminal screw torque consistently to avoid loose connections or overheating. Confirm enclosure rating and wire routing clearances before final panel closure.
