Hubbell Wiring HBL4100C7W – Frequently Asked Questions

1) What is the difference between Hubbell HBL4100P7W and HBL4100C7W?
They are the two mating halves of the same 100A pin and sleeve set. HBL4100P7W is the plug (the male pin half that goes on the cord end feeding out), and HBL4100C7W is the connector (the female sleeve half that terminates the other cord end). Both are 4-wire, 3-pole watertight devices in red. If you are building a cordset, you need one of each; if you are replacing a damaged end, order only the half that failed.
2) Will a 4-wire 3-pole 100A pin and sleeve plug work on a 480V three-phase circuit?
Yes. The Hubbell HBL4100P7W is rated 480V, 100A in a 4-wire, 3-pole configuration, which is three phase conductors plus a fourth wire for the equipment ground. That is the standard arrangement for 480V three-phase delta equipment hookups. If your load needs three phases plus a neutral AND a ground, you want a 5-wire 4-pole device instead, not this one.
3) Can these 100A pin and sleeve devices be used outdoors in the rain or in a washdown area?
Yes. Both the HBL4100P7W plug and HBL4100C7W connector use watertight construction suitable for wet locations, which covers rain, splash, and washdown exposure on industrial sites. The watertight seal depends on the device being fully mated and the cord grip properly tightened on the correct cable diameter; an unmated plug left lying on wet ground is not protected.
4) Why is this Hubbell pin and sleeve device red, and does the color matter?
Red is the pin and sleeve color code for 480V three-phase at 60Hz, and Hubbell builds the HBL4100P7W and HBL4100C7W in red to match that rating. On a site running multiple voltages, the color is how a crew tells a 480V cordset from a 208V one at a glance before they plug anything in. The color does not change the electrical rating, but mismatching colors across a distribution system defeats the point of the system.
5) Is a pin and sleeve connector the right choice for temporary construction site power, or should I use a twist-lock?
At 100A and 480V three phase, pin and sleeve is the practical choice. Twist-lock devices top out well below 100A, so they are not an option at this current. The Hubbell HBL4100 pin and sleeve devices are built for repeated connect and disconnect cycles and watertight exposure, which is exactly the duty on a temporary distribution setup feeding equipment from a panel or spider box. For permanently wired equipment that never gets unplugged, a hardwired disconnect is simpler.
6) Will the Hubbell HBL4100C7W connector mate with another manufacturer's 100A pin and sleeve plug?
The HBL4100C7W is designed to mate with corresponding Hubbell pin and sleeve plugs and receptacles in the same 4-wire 3-pole 480V 100A configuration. Pairing it across brands is not something we can confirm here, so the safe build is a matched Hubbell pair: HBL4100P7W plug to HBL4100C7W connector. Pole count, wire count, and voltage rating must match on both halves regardless.
7) Do I need anything besides the plug and connector to make up a 100A 480V cordset?
You need the cable itself and the overcurrent protection on the supply side. The Hubbell HBL4100P7W plug and HBL4100C7W connector terminate four conductors each (three poles plus ground), so your cord has to be a 4-conductor type sized for 100A at 480V, and the cord grip on each device has to suit that jacket diameter. The devices are field-wireable ends only; they do not include cable, strain relief beyond their own grip, or a disconnect.
8) Can an Ocal ST145-G liquidtight connector be used in place of the Hubbell HBL4100P7W pin and sleeve plug?
No. The Ocal ST145-G is a PVC-coated liquidtight flexible conduit connector, a raceway fitting that terminates flexible conduit into a box or enclosure. The Hubbell HBL4100P7W is a 4-wire, 3-pole watertight pin and sleeve plug rated 480V 100A that carries current and mates with a matching pin and sleeve connector for repeated connect and disconnect cycles. The two serve different functions in the same wet-location install, and the conduit fitting makes no electrical connection between conductors.
9) For a wet-location 480V 100A cord drop, what do I need besides the Hubbell pin and sleeve device?
The mating half is the first decision: the HBL4100P7W is the plug and the HBL4100C7W is the connector, both 4-wire 3-pole watertight devices, so pick the one that matches the end you are terminating. If the run transitions into flexible conduit at an enclosure, a liquidtight fitting such as the Ocal ST34-G PVC-coated steel straight connector in 3/4-inch handles that termination; it is a conduit fitting, not a current-carrying device, so it does not replace either pin and sleeve half.
10) I need a liquidtight fitting for a 3/4 inch conduit run, not a power connector. What should I look at?
A 100A pin and sleeve plug is a cord-end power device and will not serve as a conduit fitting. For a liquidtight flexible conduit termination, the Ocal ST34-G is a PVC-coated steel non-grounding liquidtight straight connector in 3/4 inch, and the Ocal ST145-G covers the same family in a larger trade size. Those thread into a box or enclosure hub; the Hubbell device connects cords to each other.
