- Yes, in a standard electrical system, you’ll often see three connections:
- Hot (Live) – This wire carries the electrical current from the power source. It’s typically black (or sometimes red).
- Neutral (Cold) – This wire completes the circuit by returning the current to the source. It’s typically white.
- Ground – This is a safety wire that provides a path for excess electricity to go into the earth if something goes wrong. It’s usually green or bare copper.
