Bryant 6372CR – Frequently Asked Questions

1) What is the difference between the Bryant 6372CR and 6374CR power inlets?
Both are 637 Series 50A power inlets, and the difference is the pole and wire configuration with its matching voltage. The 6372CR is 2-pole 3-wire rated 125V, and the 6374CR is 3-pole 4-wire rated 250V. Pick by the circuit you are feeding: a single-phase 125V feed takes the 6372CR, a 250V feed needing three poles plus a ground takes the 6374CR. They are not interchangeable, and the configurations will not mate with each other's plugs.
2) Can I use a Bryant 637 Series power inlet to connect a portable generator to a panel?
That is one of the intended uses. The 637 Series power inlet is a dedicated connection point for bringing external power into equipment, panels, distribution systems, or a portable power source, and generator and temporary power hookups are listed applications. At 50A you would choose the configuration that matches your generator's output cord end: 2-pole 3-wire 125V on the 6372CR, or 3-pole 4-wire 250V on the 6374CR.
3) I have a 240V single-phase load. Which Bryant 637 inlet do I order?
The 6374CR is the 250V device in the 637 Series and is the one to look at for a 240V system, since its 250V rating covers 240V nominal. The 6372CR is only rated 125V and must not be used on a 240V circuit. Confirm your pole count matches 3-pole 4-wire before ordering.
4) Does a 3-pole 4-wire 50A inlet mean I get three hots and a neutral, or a ground?
On the 6374CR, 3-pole 4-wire means three current-carrying poles plus a fourth conductor, which in a 3P4W device is the equipment grounding conductor rather than a neutral. If your feed needs a separate neutral in addition to a ground, a 3-pole 4-wire device is the wrong configuration and you need a 4-pole 5-wire inlet instead. The 250V rating on the 6374CR should be matched to your system voltage before you wire it in.
5) Is a Bryant 6372CR a plug or a receptacle?
It is a power inlet, not a plug or a standard receptacle. An inlet is the male-pinned device you mount on the equipment, panel, or enclosure so a power cord set can be plugged into it, so power flows in rather than out. If you need the cord end instead, you want the matching 50A plug or connector body in the same configuration, 2-pole 3-wire 125V for the 6372CR.
6) Will a 637 Series 50A inlet handle a 60 amp feed?
No. Both 637 Series inlets are rated 50A, so the overcurrent protection on the circuit has to be sized at 50A or less. Running a 60A feed through it overloads the device. For a larger feed you need a device rated for that amperage.
