Q: What does the designation “5-15R” mean for a female plug end?
A: “5-15R” refers to a NEMA 5-15 receptacle-style connector rated for 15 amps at 125 volts, grounded (2-pole + ground), which accepts a standard NEMA 5-15P plug.
Q: What key specifications should I verify when installing or replacing a 5-15R female plug end?
A: You should verify that it is rated for 15 amps and 125 volts, matches the wire gauge of the cord (commonly 18-12 AWG for 15 amps), ensures it has three conductors (hot, neutral, ground), and is UL/ETL listed for safety.
Q: What safe wiring practices should be followed when installing a replacement 5-15R female plug end?
A: Disconnect power before beginning, strip wires to the correct length, attach hot (black) to the brass terminal, neutral (white) to the silver terminal, ground (green or bare) to the green terminal, clamp the cable jacket securely in the strain relief, and verify that no bare wire is exposed.
Q: When should the female plug end be replaced rather than reused or repaired?
A: Replace it if the housing is cracked, the contacts are loose or show corrosion, the grounding terminal is missing or damaged, the cord jacket is frayed at the entry, or if the connector becomes excessively hot in use.
