  • NEMA L17-30P locking design prevents accidental disconnection
  • 3-pole 4-wire grounding ensures safe fault-current path
  • Nylon and PBT housing resists heat and impact
  • Brass terminals maintain low-resistance connections
  • Accepts up to 10 AWG cord for high-current feeds

Industrial locking plug for 30 A circuits

This LORDWORLD NEMA L17-30P plug is a 30 A, 600 V industrial-grade connector rated for 60 Hz AC supply. It uses a 3-pole, 4-wire grounding arrangement with a twist-lock action that prevents accidental disconnection. The nylon and PBT housing surrounds brass terminals for durable contact. It is intended for technicians and facilities engineers who need a secure, high-voltage power connection.

Sustained load behaviour

The plug is rated for continuous operation at its full 30 A, 600 V rating when wired with 10 AWG conductors. Brass terminals and the thermoplastic housing maintain stable contact resistance during prolonged use, while the locking mechanism resists vibration-induced loosening. No thermal derating or duty-cycle limits are specified by the manufacturer beyond the stated ratings.

Pre-installation checks

Verify that the supply circuit is a 3-pole, 4-wire grounding system matching the NEMA L17-30P configuration and that the breaker is rated for 30 A at 600 V. Confirm the cable is 10 AWG or larger to suit the back-wire terminals. Ensure the mating receptacle is the corresponding NEMA L17-30R type and that the installation complies with local electrical codes for 60 Hz industrial power.

Questions about this item

How hot does the brass-terminal L17-30P plug get when carrying a continuous 30 A load all day?

The industrial-grade nylon and PBT housing is rated for 600 V AC at 60 Hz, and the brass terminals are designed for sustained 30 A duty without overheating when wired with 10 AWG cord.

What cord gauge and wiring scheme must I already have to install this 3-pole 4-wire grounding plug?

The plug accepts up to 10 AWG conductors and requires a four-wire feed — two hots, a neutral and a ground — matching the NEMA L17-30P 30 A 600 V pinout.

Will this twist-lock L17-30P plug connect directly to the older NEMA 10-30R three-wire range outlet I have in the shop?

No — the L17-30P is a 4-wire grounding configuration (two hots, neutral, ground) while the 10-30R lacks a separate ground, so an adapter or rewiring is required.
