Air conditioning and refrigeration electrical work in Pretoria East
An air conditioner on a shared plug circuit will trip it sooner or later. We run dedicated circuits and fit isolators so it works properly.
Air conditioners and commercial fridges draw a lot of current, especially when the compressor kicks in. Plug one into a circuit that is already feeding the bedroom or the shop counter and you get tripping breakers, warm plugs, or a unit that struggles to start.
We do the electrical side of air conditioning and refrigeration. That means dedicated circuits from the DB board, isolators at the outdoor unit, and electrical connections for refrigeration in homes, shops and businesses.
Jobs we get called for
Dedicated circuits for air conditioners
Its own breaker and cable from the board, sized for the unit.
Isolators at the outdoor unit
So it can be switched off safely at the unit when it is serviced.
Refrigeration connections
Supply for display fridges, freezers and cold rooms.
Breakers tripping when the unit starts
Checked to see if the circuit is overloaded or the supply is undersized.

Common questions
Can I plug my air conditioner into a normal plug?
Small portable units are designed for that, but a fixed split unit should have its own dedicated circuit. Sharing a circuit is a common cause of tripping.
Why does the outdoor unit need an isolator?
It lets whoever works on the unit switch it off right there, without having to go back to the DB board.
Do you do commercial refrigeration wiring?
Yes. We do the electrical connections for refrigeration in shops and businesses as well as homes.
