This guide covers replacing a plug on a household appliance cord in the United States, where standard household outlets are typically 110–120 V. Plug styles, terminal layouts, and wire colors differ by country, so do not use these wiring directions outside the U.S. If the cord is damaged, the wiring is unclear, or the replacement plug will not fit and close as designed, stop and have the cord or appliance repaired by a qualified person.
Decide whether the plug can be replaced safely
Unplug the appliance before inspecting or working on its cord. If the damaged plug is still connected, switch off power at the breaker before unplugging it. Do not handle a plug or cord that may be energized.
Inspect the entire cord. A plug-only repair is appropriate only when the cord itself is sound. Fraying, cuts, exposed conductors, or signs of overheating can indicate damage beyond the plug; replace the entire cord or have the appliance repaired by a qualified person. Do not cover damaged wiring with electrical tape and fit a new plug over it. The Home Depot’s U.S. replacement guide advises against that workaround.
For workplace context, OSHA’s 29 CFR 1910.334(a)(2)(ii) says: “If there is a defect or evidence of damage that might expose an employee to injury, the defective or damaged item shall be removed from service, and no employee may use it until repairs and tests necessary to render the equipment safe have been made.” This is a workplace rule, not a household-specific legal instruction. Read OSHA’s equipment-use regulation.

Choose a compatible replacement plug
Use a replacement plug expressly suitable for the appliance cord. Match its voltage and amperage ratings to the appliance and preserve the plug’s original type and grounding arrangement. Do not remove a grounding pin or convert a three-prong plug to a two-prong plug.
- Connection style: Choose a plug compatible with the cord and follow its instructions. Replacement designs may be self-connecting or use terminal screws; the preparation and connections differ.
- Poles and grounding: Match the original two-prong or grounded three-prong configuration.
- Cord compatibility: Confirm the plug is designed for the cord’s construction and size.
- Ratings: Check the replacement plug’s voltage and amperage ratings against the appliance requirements.
If you cannot identify the plug type, cord construction, or required connections, do not guess. Use the appliance manufacturer’s guidance or ask a qualified repair professional.

Replace the plug on a U.S. appliance cord
The following sequence is for a compatible replacement plug on a sound cord. The exact procedure depends on the plug design; use the instructions supplied with the plug you bought. The Home Depot guide describes U.S. polarized two-prong and three-wire grounded examples, not a universal wiring standard.
- Isolate the appliance. Unplug it. If the plug is still connected, switch off power at the breaker before unplugging it.
- Cut off the old plug. Once the appliance is isolated and the cord has passed inspection, cut the cord cleanly behind the damaged plug.
- Prepare the replacement housing. Open the plug and thread the cord through the housing in the order required by that model. Some designs require the housing to be on the cord before conductors are prepared.
- Prepare conductors only as directed. For terminal-screw plugs, strip the outer jacket and conductor insulation to the lengths specified by the plug manufacturer. Avoid nicking or cutting conductor strands. Hong Kong Labour Department guidance likewise stresses careful stripping without damaging strands; its plug-specific instructions should not be treated as U.S. wiring directions.
- Connect each conductor to its identified terminal. On the U.S. polarized two-wire example, the ribbed neutral conductor connects to the silver terminal and the smooth hot conductor to the brass terminal. On the U.S. three-wire example, black (hot) connects to brass, white (neutral) to silver, and green (ground) to the grounding screw. Confirm the markings and directions on your particular plug; do not infer connections from these examples if your cord differs.
- Secure the cord jacket. Tighten the plug’s strain relief or cord clamp over the outer jacket, not the individual insulated conductors. The jacket must be held so that a pull on the cord does not tug directly on the terminal connections.
- Close the housing fully. Reassemble the plug as instructed. If the housing does not close completely, the cord clamp does not hold the jacket, or any connection is uncertain, stop and correct the problem before use.
Why these wiring directions are U.S.-specific
Plug shapes, terminal positions, and conductor color conventions vary by jurisdiction. For example, WorkSafe New Zealand recommends using appliances with moulded plugs that do not need rewiring and warns that incorrectly positioned wires can cause serious electric shocks. ESKOM’s South African example identifies green/yellow as earth, blue as neutral, and brown as live. Those examples reinforce why local instructions matter; they are not substitutes for the U.S. connections described above.
