What this usually means

People often describe these as just a small part, but they still sit on a live circuit and need the right rating, safe termination and proper testing. Small does not mean casual.

Typical solutions

  • Replace worn or broken small components like-for-like where the existing point is otherwise suitable.
  • Correct loose terminations, poor fit or unsuitable parts discovered during inspection.
  • Confirm the replacement suits the location and intended use before handover.

Basic information

  • A low-cost part can still hide heat damage, brittle insulation or the wrong previous accessory.
  • Location matters, especially in kitchens, bathrooms and utility areas.
