whole installation illegal.
mains (as single RCD) cannot 100mA. Max 30mA (0.03A)
WH missing any 10mA RCD/RCBO for the WH circuit. Illegal. Can die one. Many ppl die liao. https://www.nst.com.my/news/nation/2020/08/...e-electrocution

Find a way to slot a RCBO in since ur DB box pretty full. Lights can combine since not critical and won't overload.
If more than one water heater suggest get a new DB box. U are missing the most important and most expensive elements.

U will need the CC225B for each water heater

Spending thousands on insurance agent premiums on yearly basis but not spending one-off (ok la 30-40 years change) on proper electrical safety?

Forgot to mention this is 2nd DB box which is installed on newly extend area. The DB box not really full. He standby the slot in case next time I need add on.

So I need
1. Change 100mA to 30mA
2. Install CC225B for each heater?

I ask the electrician what thing he use for water heater, he say is 20A. No any detail about 10mA or even 20mA. Just 20A
