Hi there, my house is a 3 stories terrace with 3 phase electric supply. Developer gave 0.3A RCCB. Is it safe?
Wow, not bad that the developer give HAGER!

For single phase the RCCB is 100mA for power and 30mA for lighting. For water heater it is 10mA.
If 3-phase the main RCCB is 300mA (effectively 100mA per single phase) and 100mA (around 33mA for single phase). Dont think there is any application for 3-phase heater in a residential home. This post has been edited by brutus: Mar 19 2023, 07:55 PM |

QUOTE(RagingCandy @ Mar 19 2023, 01:53 PM) Means using 300mA RCCB is okay? Noob here For a 3-phase supply, yes it is OK. But if you have instant/storage heater, run a different RCCB of 10mA (either 16A or 20A) for best protection.For my own home I have individual RCCB for: 1) Power Circuit (63A 100mA) 2) Lighting Circuit (25A 30mA) 3) Solar Heater Circuit (16A 10mA) Mine is on single phase setup. |
