Leviton 5278-CWP – Frequently Asked Questions

1) What amperage and voltage is the Leviton 5278-CWP power inlet rated for?
The Leviton 5278-CWP power inlet receptacle is rated 15A at 125V, 2-pole, 3-wire (hot, neutral, ground). That means it suits single-phase 120V circuits on a 15A branch only. If the equipment you are feeding draws more than 15A, or runs on 250V, this is the wrong inlet and you need a higher-rated device.
2) What is the difference between a power inlet and a regular receptacle, and which do I need?
A standard receptacle takes power from the building wiring and hands it out to a cord. An inlet works the other way: the 5278-CWP is a fixed device mounted on equipment, a panel, or an enclosure so an incoming cord from a portable or temporary source can be plugged into it. If you are bringing power INTO a machine, skid, or distribution box, you want the inlet. If you are feeding a tool or cord from the building, you want an ordinary receptacle instead.
3) Will a standard 15A 120V cord plug mate with this Leviton inlet?
It is a straight blade configuration, 2-pole 3-wire at 15A/125V, so it mates with a matching straight blade connector body of the same rating and configuration. Straight blade is not interchangeable with locking (twist-lock) devices, so a locking cord cap will not engage it. Match the configuration on both ends of the cord assembly.
4) Is this an industrial grade device or just commercial spec?
Leviton builds the 5278-CWP to industrial grade, which is the heavier of the common wiring device grades and intended for repeated plug cycles in commercial and industrial service. For an MRO or facilities buyer standardizing on one grade across equipment, this sits above residential and spec/commercial grade devices.
5) What part number do I order for the Leviton 15A 125V straight blade power inlet?
Order Leviton 5278-CWP. It is a single-model device, so there are no finish, color, or amperage options to specify on the order; the 15A 125V gray industrial inlet is the whole of it.
6) Can an electrician use this on a generator or temporary job-site power feed?
That is one of its intended uses. As a fixed inlet rated 15A at 125V, it gives a defined connection point where a portable or temporary power source lands into equipment or a distribution setup, which covers job-site gear and panel-mounted inlet applications. Keep the branch circuit and cord sized to the 15A rating, and have it installed by a qualified electrician as part of the larger power connection assembly.
7) What color is the Leviton 5278-CWP inlet?
Gray. That is the only color offered on the 5278-CWP, so if you are matching a run of devices across equipment panels, expect gray housings throughout rather than the black or white used on some other lines.
