Was finding an electrician to install heater and air-cond.

Then suddenly wondering how many electrician outside was really having a license or certificate. Is there a way to find/verify if the electrician is licensed or certified in Malaysia?

Do we able to find licensed/certified electrician to do kacang putih home works? or they only for those big projects?

For small scope as mentioned anyone will do but it has to be done right lah.
Like not skimping on the ODU-IDU 4 wires so that inverter AC can be installed safely. And WH is more important (if no 10mA RCD have to add for safety). If already have ready point then hooking up doesn't need much skill.
