Asking for help from electricians or DIY pros.

My house still has a few of these kind of magnetic starters for the AC units. Are they still necessary for newer AC? Can I just replace them with those 15A or 20A water heater switches? How many amps are needed for AC?

i use a 20A switch for mine

for modern aircon they are not needed anymore.

15A switch is more than enough unless your aircon is big hp.

1HP can use 15A?

can, no problem.

Thx.

I believe that what you called magnetic starter is mostly nothing more than magnetic contactor. The magnetic contactor is nothing more than just a switch that make contact on magnetic action. Usually this contactor has current rating depends on the rating of the motor.

A 1 hp air-cond has adequate soft start circuitry that will prevent massive current surge during start. So, normal 15A socket will do. Even good 13A socket also can work.

That national remote still working?

shaddap la

your 15A or 20A Sw finally also connect to 20A MCB.

Yes u can just change with 20A switches, but if the aircond malfunction it will trip at the switch but trip at MCB.

Ownself DIY costs less than RM40

Oh btw u might need to buy the switch casing coz that existing switch does not look like have casing in the wall.

Not my picture. I just took off google cuz I'm at the office.

Changed my last magnetic switch air-cond just before the MCO started. Panasonic, 20+ years

Yah.. gonna fix myself. Any particular brand I should aim for? I heard UMS is good quality but they look basic as hell - grandpa style. And Schneider's is freaking expensive. Any that is a happy medium between good quality and good looks? I prefer a smooth modern switch.

Schneider would be the most common brand i guess. They have few lines just see which design u prefer.

I just bought one few weeks ago for RM25 plain white ones with led. There are cheaper selling in Shopee but duno imitation or original.

Beware there are many imitation so if u buy online better buy from MALL seller just to be safe.
Else just go to any reputable DIY shops or local chinese hardware shops.
