Like-for-like swaps

Replacing a standard receptacle with another standard receptacle, or a single-pole switch with another single-pole switch, with power off and a tester verifying off, is allowed for homeowners in MD, DC, and VA.

What to buy

  • 15A or 20A spec-grade receptacles (avoid budget builder-grade)
  • Tamper-resistant in living areas
  • Decora-style switches and outlets if you prefer the look
  • Lutron Caséta or Diva for any switch you'll dim

Tools

  • Voltage tester (non-contact + plug-in)
  • Insulated screwdrivers
  • Wire strippers
  • Linesman pliers
  • Headlamp

Procedure

  1. Confirm power is off at the breaker (tester both probes).
  2. Unscrew and pull the device out.
  3. Note wire positions: hot (black/red), neutral (white), ground (green/bare).
  4. Use side-screw terminals, not backstabs. Wrap clockwise around the screw.
  5. Torque to spec.
  6. Fold wires in, reinstall, restore power, test.

When to stop and call

  • Aluminum branch wiring (silvery solid wire, not copper)
  • Three or more cables in one box
  • Backstabbed wires that won't release
  • Burnt insulation or melted plastic
  • Anything 3-way or 4-way unless you've done one before
