Cooper Wiring Devices 6709N – Frequently Asked Questions

1) Will a Cooper 6709N connector mate with a NEMA 6-50 welder plug?
Yes. The Cooper 6709N is a NEMA 6-50R configuration, two-pole three-wire grounding, so it accepts any 6-50P plug, which is the standard cap on 250V stick and MIG welders. It is the female end of a cord assembly, not a panel-mounted receptacle.
2) What size cord can I terminate in the 6709N connector?
Wire range is #12 through #4 AWG, which covers 6 AWG and 8 AWG SO cord typical of 50A welder and range leads, and lets you go up to #4 on long runs where voltage drop matters. The auto grip feature clamps the cord jacket so the pull is taken off the brass terminations.
3) Can I use a 6-50R connector on a 120/240V circuit that needs a neutral?
No. The 6709N is two-pole, three-wire grounding: two hots and an equipment ground, no neutral. It serves 250V two-wire loads only, such as welders and heaters. If the equipment needs 120V as well as 240V, you need a four-wire configuration like a 14-50, not this connector.
4) I need a field-attachable connector for a 120V extension cord, not a 50A circuit - what should I order instead of the 6709N?
The Cooper 6709N is built for 250V, 50A two-pole, three-wire grounding circuits and accepts #12 to #4 AWG conductors, which is oversized for a standard 120V cord. For a 125V, 15A cord end, the Eaton Arrow Hart 1547 is a straight blade connector in NEMA 5-15R, the standard three-prong 120V configuration, and is a Severe Duty grade device for jobsite use.
5) Can I use the Eaton Arrow Hart 1547 connector in place of the Cooper 6709N on a 250V welder circuit?
No. The Cooper 6709N is a NEMA 6-50R connector rated 250V and 50A, which is the configuration used for welders and other heavy-amperage 250V equipment. The Eaton Arrow Hart 1547 is a straight blade connector in NEMA 5-15R at 15A, 125V - a standard household-style configuration that will not mate with a 6-50P plug and is not rated for the load. For a 250V, 50A cord assembly, the 6-50R configuration is the one to order.
6) Is this a receptacle for the wall or a cord-end connector?
It is a cord-end connector, field attachable, meant to land on the end of a portable cord or extension assembly. Design type is connector, so there is no strap or yoke for a device box. For a fixed 50A outlet in a wall or panel you want a flush or surface receptacle instead.
7) Will a nylon connector body hold up in a shop or on a generator cart?
The housing is nylon, which takes impact and abrasion better than thermoplastic on dragged cords, and the contacts are brass. Body color is black, which is the usual way crews tell a 250V lead apart from a 125V one on a cart full of cords.
8) Can I order the 6709N in another color or amperage?
No options to pick. Model 6709N is a single configuration: black nylon, 50A, 250V, 6-50R. There is nothing to specify beyond the part number.
9) How does the housing on the Cooper 6709N compare to a severe duty connector like the Eaton 1547?
The Cooper 6709N uses a black nylon housing with brass contacts and an auto grip cord-retention feature that clamps the cord at the connector to take strain off the terminations. The Eaton Arrow Hart 1547 is classified as a Severe Duty grade straight blade connector. Both are intended for rough service, so the deciding factor is usually the configuration and rating rather than the shell: the 6709N is the 6-50R, 250V/50A device, and the 1547 is the 5-15R, 125V/15A device.
