License 7/81470
Power failure at midnight, a burning smell from the DB box or a socket that keeps tripping? Our EMA Licensed Electrical Workers attend emergency call-outs across Singapore around the clock — HDB flats, condominiums, landed homes and commercial units.
Wireman (Sin & Goh Electrical Engineering) is a Singapore electrical contractor working under EMA Licensed Electrical Worker licence 7/81470. We take emergency calls 24 hours a day, every day of the year, and attend islandwide. Emergency call-out and attendance is S$100 – S$200 including travel, with the repair quoted to you on site before any work begins. Call or WhatsApp +65 9025 0076.
These faults carry a fire or electrocution risk and should not wait until the next working day.
A hot plastic or fishy smell at the distribution board usually means a loose terminal or a scorched connector heating up behind the cover. Switch off the main switch if it is safe to reach.
Scorch marks, buzzing or sparking at a socket, switch or light fitting indicate arcing. Stop using that point entirely and do not plug anything else into it.
If your neighbours still have power, the fault is inside your own installation — a tripped main RCCB, a failed breaker or an incoming supply issue that needs a licensed worker.
A main breaker that will not stay up, or trips again within minutes, is detecting real earth leakage. Forcing it up repeatedly damages the breaker and hides a live fault.
Ceiling leaks, a flooded kitchen or a wet bathroom socket can energise surrounding metalwork. Keep everyone clear of the area and isolate the circuit if you can do so safely.
Cables damaged during renovation, chewed by pests or hanging loose from a ceiling need to be isolated and made safe by a licensed electrician before power is restored.
No hidden costs. You get an upfront quotation on site before any repair work starts.

*Rates vary with property type (landed > condominium > HDB) and job complexity. Parts are quoted separately once the fault is identified.
Problem: The homeowner reported a strong burning smell coming from the distribution board late at night.
Solution: Our EMA Licensed Electrical Worker attended on site and traced the smell to a burnt VI connector, loose wire terminations and a poor original wiring layout inside the DB box. The wiring was re-arranged, the damaged components replaced, and power was safely restored within two hours.
Problem: The main RCCB tripped the moment the bathroom water heater was switched on, cutting power to the whole flat.
Solution: Insulation testing confirmed earth leakage from a degraded heating element, with a partially melted double-pole isolator switch adding resistance on the same circuit. The isolator was replaced, the heater circuit re-tested, and the homeowner was advised on replacing the failing heater unit.
"We are very happy with Mr Sin's services. He patiently checked the various possible causes for the malfunction of our electrical socket in my bedroom… Mr Sin finally found the cause. Thank you!"

We attend HDB flats, condominiums, landed homes, offices and industrial units across Singapore, including:
Yes. We take emergency calls 24 hours a day, 7 days a week, including weekends and Singapore public holidays. Call or WhatsApp +65 9025 0076 and you will speak to a licensed electrician rather than an answering service.
Frequent tripping is usually caused by a faulty appliance, current leakage through damaged or ageing wiring, moisture in a socket or conduit, or a circuit carrying more load than it was designed for. Take note of any appliance plugged in shortly before the tripping started — that is the single most common cause.
A heater that trips the RCCB usually points to a degraded heating element leaking current to earth, an oxidised or melted double-pole isolator switch, or cable that is undersized for the heater's current draw. Stop using the heater until it has been tested — an earth leakage fault is a shock risk, not just an inconvenience.
A few things make the visit faster and safer:
If the unit's load demand exceeds 45 kVA, SP Group and EMA regulations require an EMA Licensed Electrical Worker to assess the total load, endorse the single-line diagram and submit the application on your behalf. You cannot apply directly through the consumer portal. We handle this submission for commercial and industrial tenants.
Yes. All work is carried out under EMA Licensed Electrical Worker licence number 7/81470, with more than 20 years of field experience across HDB flats, condominiums, landed homes and commercial units in Singapore.
