Cooper Wiring Devices 4700 – Frequently Asked Questions

1) Will the Cooper 4700 locking connector mate with my existing twist-lock cord caps?
The Cooper Wiring Devices 4700 Safety Grip connector is a NEMA L5-15 device, so it mates only with L5-15 plugs and inlets, 125V, 15A, two-pole three-wire. If the plug on your equipment is an L5-20, L5-30, or L6-series, the blade pattern will not engage. Check the configuration stamped on the existing plug before ordering.
2) What wire size can I terminate in the Cooper 4700 connector?
It accepts #14 through #10 AWG conductors, which covers 15A and 20A branch-circuit wire and the common 14/3 and 12/3 SJ or SO cord sizes used for portable drops. Termination can be made from the back or the side, so you can bring the conductors in whichever way suits the cord grip.
3) Is this a connector (female) or a plug (male)?
The 4700 is the connector, the female body that goes on the end of a cord to receive an L5-15 plug. If you need the male end for the supply side of a cord set, you want an L5-15 plug instead, not this part.
4) Can I use this connector on a 240V or three-phase circuit?
No. It is rated 125V only, two-pole three-wire, so it is a single-phase 120V device with an equipment ground. For 125/250V work the Eaton Arrow Hart Ultra-Grip L14-20 connector is a 20A 125/250V device, and the Leviton 2413 is a four-wire three-pole 125/250V connector. For a five-wire four-pole 20A layout, Leviton's 2323 covers that.
5) I need a 240V locking connector for a machine, not 125V. What are my options?
The Cooper 4700 is a 125V, two-pole, three-wire device in NEMA L5-15, which is a 125V-only configuration. For higher-voltage work, the Eaton L530C Arrow Hart Ultra Grip is a 30A two-pole, three-wire nylon connector in the L6-30 series, and the Eaton L1420-C Ultra-Grip is a 20A 125/250V connector in NEMA L14-20 for four-wire 125/250V cords. Pick by the configuration stamped on the mating receptacle.
6) Can I use the Eaton L1420-C in place of the Cooper 4700 on a job site extension cord set?
No. The Cooper 4700 is a 125V, 15A two-pole, three-wire connector in NEMA L5-15, which suits portable power distribution and temporary job site cord sets on #14-10 AWG conductors. The Eaton L1420-C Ultra-Grip is a 20A 125/250V commercial grade connector in NEMA L14-20, a four-wire 125/250V pattern. The two configurations do not intermate, so it is not a substitute for an L5-15 cord cap.
7) Is a nylon-bodied locking connector tough enough for job-site and shop use?
The housing is glass-filled nylon with brass contacts, built for industrial handling and repeated connect and disconnect cycles. Nylon bodies are the usual choice for portable cord sets and temporary power because they are non-metallic and take impact without denting. For heavier abuse where a boot or clamp-style grip is wanted, Bryant's 7 Series non-metallic locking connector (71020NC) is another non-metallic option.
8) Why choose a twist-lock connector over a standard straight-blade cord connector?
A twist-lock body rotates into the plug and holds mechanically, so vibration from machinery or someone walking into the cord won't pull the connection apart. That is why L5-15 is specified on shop equipment and temporary power drops instead of a 5-15 straight blade. The tradeoff is that both ends have to be the same locking configuration, so you cannot plug an ordinary 5-15 cord cap into it.
9) Is the L1-15 connector the same thing as this L5-15?
No, and it's an easy mix-up. L1-15 is a two-wire, non-grounding locking configuration; the 4700 is L5-15, three-wire with a ground. The Eaton 7506 is the L1-15 device if that is genuinely what your existing plug is. They will not intermate.
10) What is the difference between the Cooper 4700 and the Leviton 2413 or 2423 locking connectors?
The Cooper 4700 is a two-pole, three-wire 125V, 15A connector in NEMA L5-15. The Leviton 2413 is a four-wire, three-pole industrial locking connector rated 125/250V, which is a different pole count and wire count for three-phase or 125/250V cords. The Leviton 2423 is an industrial grade locking connector in black and white. Pole and wire count have to match the cord and the receptacle, so the 2413 is not a drop-in for an L5-15 opening.
11) For heavy industrial duty, is the Cooper 4700 or the Eaton 7506 the tougher connector?
Both are built for industrial service. The Cooper 4700 Safety Grip is specified for industrial applications with brass contacts and a glass-filled nylon housing, wired from the back or the side on #14-10 AWG. The Eaton 7506 carries an extra heavy-duty industrial specification grade designation. The deciding factor is configuration, not toughness: the Cooper 4700 is L5-15 and the Eaton 7506 is L1-15, so they serve different mating devices.
12) Which locking connector do I need for a 4-pole 5-wire cord?
The Cooper 4700 is a two-pole, three-wire device and cannot terminate a five-wire cord. For that, the Leviton 2323 is a 5-wire, 4-pole industrial grade locking connector rated 20A. Use the Cooper 4700 only where the circuit is 125V, 15A with a hot, neutral and ground on #14-10 AWG conductors.
13) Are there non-metallic locking connector alternatives to the Cooper 4700 Safety Grip?
The Cooper 4700 already uses a glass-filled nylon housing with brass contacts, so it is a non-metallic bodied device. If you are standardizing on another line, the Bryant 71020NC is a 7 Series non-metallic NEMA locking connector, and the Bryant P468365 is a 705 Series locking connector offered in NEMA twist-lock configurations. Match the NEMA configuration code to the Cooper's L5-15 if it is replacing one in an existing cord set.
14) What is the Cooper part number and color for this L5-15 Safety Grip connector?
Cooper Wiring Devices model 4700, black housing. It is sold as a single model with no finish or size options, so the one part number covers it.
