Electrician in Cheras

Dispatcher does not do the work. You pick the business, and they do the job.

What ST asks for when a water heater goes in

Suruhanjaya Tenaga (ST) is the energy regulator. Its guideline for water heaters (GP/ST/No.6/2016) sets out these points:

• Own circuit. The heater gets a circuit that feeds nothing else.
• Own safety switch. That circuit has a breaker with an RCD that trips at 10 mA or less.
• The right person. An ST-registered electrical contractor or wireman does the wiring.
• The right hose. The shower hose must not be metal or chrome.
• A test at the end. The earth path is tested before you use it.

A plumber can fit the pipes. The wiring side is for an electrical contractor.

Keep it safe after it goes in

ST gives this care routine in the guideline and in its safety advice:

If the RCD does not trip when you press the button, call an electrician.

The heater trips the power. What now?

1. Switch off the heater at its own switch.
2. At the DB box, switch the RCD back on.
3. If the power stays on with the heater off, the fault is likely in the heater or its circuit.
4. Leave the heater off and ask an electrician to test it.

If the whole street is dark, it is not your heater. Call TNB on 15454.

How to check who fits your heater

• ✓ Find the firm on the ST list of registered contractors.
• ✓ Ask if the heater will get its own circuit and RCD.
• ✓ Ask which hose they will fit.
• ✓ Ask them to test the earth when they finish.
• ✓ Get the price in writing before work starts.

Dispatcher has not checked these yet. Do this check yourself.

When to call an electrician about your heater

Call one if your heater shares a circuit, has no RCD of its own, uses a metal or chrome hose, or keeps tripping. Ask for their ST registration before they start, and ask them to show you the earth test.
