As per title, been using this for more than 10 years in my house, old house layout where the switch for heater is in my room
Recently it burnt, so it concerned me as is it ok to use 13a for this water heater, or it's best to change to the 20a on off switch, or the 15a round plug and socket? Thanks!
Here is a snapshot from Suruhanjaya Tenaga's Water Heater Installation Guideline. Not just uncertified technicians, but even many developers are still providing new properties with 3-pin socket in the bathroom, which is very irresponsible. Let's remind one another to STOP using 3-pin plugs for water heaters, and connect the water heater directly to the main power supply (with the correct cable size depending on the water heater's power rating, refer to the next screenshot below).Recently it burnt, so it concerned me as is it ok to use 13a for this water heater, or it's best to change to the 20a on off switch, or the 15a round plug and socket?

If you are worry that removing the 3-pin socket will leave a hole in your bathroom wall, you can use a water heater connector to directly replace the 3-pin socket using the same junction box, as suggested by davidlow7 below, such as SIRIM / Suruhanjaya Tenaga certified water heater connector brands like STEC and CENTON. Here is one example from Shopee.

Yeap - if you can invest in this product is even better - to replace the 15A plug.

Tumpang question since same power rating 3300w.
Is the below safe?
Use this table below to determine the cable size / switch you should be using based on the power rating of your water heater, as recommended by Suruhanjaya Tenaga.Is the below safe?
