- For indoor walls near the air conditioner.
- Also available ready with a 20A socket, as our 20A SPN AC box.
An AC box gives an air conditioner its own heavy-duty plug point with local switching. This is the empty version: the enclosure alone, for electricians who fit their own socket and MCB. SPN means single phase and neutral — the normal supply for home and office ACs.
For a ready solution, choose our 20A SPN AC box, which comes with a 20A socket. Ask us if you want to confirm that a particular socket or MCB fits this box before you order.
Whatever you fit, the circuit must be earthed and protected by an MCB rated for the AC and the cable.
Where to use it
- Making up AC points with your own socket and MCB.
- Replacing a damaged AC box while reusing a good socket.
- Contractors wiring many AC points to one standard.
How to install
- Switch off the supply and fix the box on the wall near the AC.
- Fit the socket and MCB you have chosen, following their markings.
- Bring in a dedicated circuit, connect phase, neutral and earth, close the cover and test.
Electrical work should be done by a licensed electrician with the supply switched off. The AC circuit must be earthed and protected by a suitably rated MCB.
