The LEGRAND 1031 is a 3-pole, 3-wire (3P3W) straight-blade plug rated at 30 amps and 125/250 volts. It is designed for use in industrial and commercial power distribution applications where a reliable, code-rated connection between portable equipment and a wiring device is required. Electricians and maintenance technicians install this plug on the cord end of equipment, generators, welders, or HVAC units that draw heavy single-phase loads. The 30-amp, 125/250-volt rating places it in the NEMA 10-30 configuration family, making it a common choice for hardwired equipment connections in commercial settings.
This plug is suited for 3-wire, single-phase branch circuits in both commercial and light industrial environments. Typical applications include connection of portable power equipment, large appliances, and HVAC or electrical service equipment to dedicated 30-amp circuits. It is installed by licensed electricians during new equipment hookups or cord replacements.
Designed as an OEM-style replacement or field-install plug for 3-pole, 3-wire 30-amp, 125/250-volt cord-and-plug connected equipment and branch circuits.
Installation should be performed by a licensed electrician in accordance with NFPA 70 (NEC) requirements for cord-and-plug connected equipment. De-energize the circuit and verify zero voltage at the receptacle before beginning work. Ensure conductor gauge matches the 30-amp circuit rating and that strain relief is properly secured to prevent pull-through at the cord grip. Do not exceed the rated amperage or voltage of the plug.
