Most Dubai homes have DP switches, the double pole isolators with a red light that control water heaters, split AC units, cookers and pumps. They carry heavy loads and often burn out or stop working. We replace faulty DP switches and boxes, check the cable behind them and test the appliance they control.

Ratings
| Appliance | Typical Rating | Notes |
|---|---|---|
| Water Heater | 20A | Often outside the bathroom |
| Split AC Unit | 20A to 32A | Depends on unit size |
| Cooker | 45A | Cooker control unit |
| Water Pump | 20A | Villa pump rooms |
Water heaters and AC units draw high current for long periods. A slightly loose terminal heats up and slowly burns the switch. We replace the switch and trim back any heat-damaged cable.
We always match the switch rating to the circuit and appliance, never just to what was there before.

An electrical repair visit starts from AED 150, and replacing a socket or switch starts from AED 60 per point. Larger jobs are quoted after the fault is found. Prices vary and can change depending on your exact requirements, the materials and access to the property, so the final price is confirmed after we see photos or visit.
You can reset it once. If it trips again straight away, leave it off and unplug appliances on that circuit. Repeated resetting can hide a dangerous fault.
We are open every day from 8am to 10pm and prioritise urgent electrical faults within those hours, with same-day visits where possible. For sparks, smoke or fire, switch off the main breaker, leave the area and call Dubai Civil Defence on 997.
