Industrial Power Distribution

The Milspec molded Quad-Box delivers four 15/20A-125V T-slot receptacles from a single NEMA 5-15P plug. It suits crews needing multiple tool connections on a jobsite or in a workshop where outlet count is limited. The 12 AWG supply cord handles up to 15 A continuous load. Builders who need more than four outlets or a higher branch-circuit rating must look elsewhere.

Thermal and Electrical Behaviour

The solid PVC housing resists dents and collapse, protecting internal conductors from impact that can increase resistance and heat. Molded construction eliminates air gaps found in hollow boxes, helping maintain consistent contact pressure under load. The 12 AWG cord is rated for the 15 A maximum current, so voltage drop stays low across the 6 ft length during normal operation.

What the Bundle Changes

The integrated quad-box replaces a separate power strip and short extension cord, reducing connection points where loosening can occur. Four T-slot receptacles accept both straight-blade and 20 A locking plugs without adapters. The single straight plug feeds all outlets, so only one wall receptacle is consumed. No software or active components are included.

Questions about this item

How do I connect the NEMA 5-15P plug to a standard wall outlet and avoid a loose fit?

Insert the straight NEMA 5-15P male plug fully into a 125 V receptacle until the blades seat firmly; the moulded strain relief prevents the cord from pulling out at an angle.

When should I replace the 12 AWG cord or the quad-box housing?

Replace the assembly if the PVC housing cracks, the strain relief tears, or the copper conductors become visible through the jacket.

What happens first if I run all four outlets at 15 A continuously?

The 15 A plug rating limits total draw, so the upstream breaker or fuse will trip before the 20 A T-slot receptacles reach their individual rating.
