Good idea, but it's troublesome to change to bigger DB Box and find the neutral wire dedicated for the water heater and need also separate the neutral bar for just water heater.
For simplicity i just change the socket or plug with built-in RCBO according to usage amphere. All of my water heaters and air conditioners are with RCBO either with socket or plug. Much easier I have this 10mA but only 13A for water heater.  This post has been edited by amco: Aug 29 2020, 03:28 AM |

QUOTE(ceo684 @ Aug 29 2020, 03:46 AM) That may work for aircon but WH at 3300W / 230V = 14.3A, 3600W = 15.6A which is a fire hazard to knowingly overload the 13A socket. Actually, I am using China's plug & socket which is 16A for water heater with tank. That 13A is suitable for AC and tankless water heater.Schneider 1-DIN module RCBO is available so it is just direct replacement of the WH MCB in DB box.  |

QUOTE(mushigen @ May 17 2023, 01:22 PM) I don't understand this statement. This is untrue. ST requires 10ma RCCB for all type of water heater. Plug and socket for water heater inside toilet is banned. I know why it's banned.Latest Guideline for water heater |
