How they differ

  • NEMA 1-15R connector Confirm the NEMA designation from the device or connector documentation rather than relying on slot shape alone.
  • NEMA 5-15R receptacle Identify the receptacle type and use qualified electrical guidance for installation or circuit work.

Then askIs the documented receptacle/connector the non-grounding 1-15R configuration or grounded 5-15R?

Trace 6 claims to their source records

C186A · P186

Hubbell/Bryant describes the NEMA 5-15R receptacle form in its wiring-device identification guidance.

Claim scope: V36 catalogue-expansion identification fact only; not independent technical approval, fabrication data, wiring instruction or end-to-end compatibility proof.

Source links: S196 · Evidence trail → (private workspace)

C186B · P186

Leviton identifies 515CV as a grounded NEMA 5-15R cord connector, with two poles, three wires and a 15 A / 125 VAC component rating.

Claim scope: Exact cord-mounted connector role. This is not a fixed wall receptacle or a complete cord assembly. No installation or electrical work approval.

Source links: S636 · Evidence trail → (private workspace)

C186C · P186

The 515CV product page says its ratings and NEMA identification are permanently marked on the device.

Claim scope: A documented marking policy does not confirm the identity, condition, authenticity or installation of an unknown part. No terminal or polarity map is supplied.

C272A · P272

Leviton identifies 102-WP as a NEMA 1-15R, 15 A, 125 V, 2-pole 2-wire polarized non-grounding connector.

Claim scope: V47 identification fact only; the cited product establishes the named connector/configuration and narrow position/conductor context, not universal wiring, mating, installation safety or interchangeability.
