How do I know if my home has single-phase or three-phase power?

Head to your meter box, open it up, and take a look:

  • If you see three main switches or three fuse cartridges, you have three-phase power.
  • If you only see one main switch, you have a single-phase connection.

Still not sure? A qualified electrician can help confirm this for you.
