nema 14-50 plug
NEMA Power Plug Sourcing is an independent sourcing partner. We help you write a nema 14-50 plug duty, take that written duty to factories that mould this family, and return quotations you can compare. We do not manufacture wiring devices, keep a price list or hold certified stock.
A 14-50 device is three-pole, four-wire, 125/250 V AC. Neighbouring 6-50 and 10-50 faces share the 50 A number and will not mate. Ampere rating, voltage class, pole count, grounding method and indoor or outdoor body stay your decisions; factories answer against those lines rather than against a catalogue nickname.
Request Factory QuotesWhat are you comparing?
- Configuration code with the trailing P or R, plus voltage stated as AC with phase if the site is not single-phase
- Cord outside diameter and conductor size in AWG so strain relief and terminals can be priced as one assembly
- Sample, quantity and delivery scope so each factory prices the same order shape
Procurement questions before a nema 14-50 plug quote
Which purchasing requirements separate nema 14-50 plug from neighbouring nema power plugs and receptacles options?
Write the configuration family first. A 14-50 request names a three-pole four-wire 125/250 V straight-blade pair. A 5-15 or 5-20 device is a 125 V household face. A locking device begins with L and twists into place. A recreational-vehicle 30 A connection is a different two-pole three-wire 125 V mould. If you only send “50 amp”, factories may quote three faces that look similar and will not connect. We keep the family, the trailing letter and the quantity of each half as separate lines.
What does an independent sourcing request for nema 14-50 plug have to contain before factories can answer it?
Factories need product type and intended application; quantity by specification and unit; configuration code; rated voltage, current and poles; cord diameter and conductor size in AWG; indoor or outdoor location written as a NEMA type rather than as an IP code “equivalent”; destination and requested delivery window; plus any documents or samples you will require. Optional budget and supplier preference may be added. We restate those lines for every supplier so a cheaper two-pole substitute is not compared against a four-wire spec.
Which part of the nema 14-50 plug specification stays the buyer’s decision?
You approve the written duty, the commercial terms and whether a quoted model is acceptable. We do not sign electrical design, destination approval or installation. Listing files attach to a catalogue number, not to this website. Dielectric strength, temperature range and flammability class on one manufacturer’s data sheet are proof that those axes exist; they are not our stock and not a supply commitment.
Who is buying NEMA power plugs and receptacles
Project buyers
Work from a device schedule and need the same configuration on both halves of a cord set, including generator inlet boxes when the drawing calls for a wall device rather than a cord-mounted male.
OEM builders
Need repeat parts that fit a fixed cord diameter and terminal style so later lots can be compared with the first approved sample without treating a family brochure as model evidence.
Facility teams
Need a replacement that lands the same conductors and weather rating as the existing inlet or receptacle, including outdoor generator bays when that is the actual site.
Checks we write onto a nema 14-50 plug brief
Rating
Confirm voltage class, ampere figure and whether the site needs a neutral. Current in A is not interrupting capacity in kA.
Protection
Confirm indoor versus outdoor body and the weather rating as a NEMA type. An IP figure is a separate system, not a translation.
Interface
Confirm terminals, cord clamp range, angle versus straight body and how the equipment ground is made.
Files
List documents to confirm per model. We have verified no listings in this batch and publish no badges.
