hi guys,
i'm seeking advice on my upcoming DB replacement & SPD upgrade to more reliable Hager parts (for electric trip reduction). Read most of the posts here and but i'm still not clear if it is okay to use RCCB 40A rate? My current setup (not sure why 63A isolator is used by the developer): 
thanks thanks This post has been edited by Octopuz: Jun 27 2017, 11:02 PM |

QUOTE(Richard @ Jun 28 2017, 03:34 AM) with respect to the guidelines set by ST.. another or replace current 100mA 40A RCD with 30mA sensitivity.- you should have another 30mA RCD strictly for the 13A 3 pin sockets (to be on a 20A mcb circuit) - the 63A isolator is ok for 16mm2 intercabling but a 40A is preferable to use 10mm2 cables.. Its easier to install.. Why are you thinking to install an SPD?  so as for the RCD current rate, i shouldn't change it to 63A type right? what's the gain of installing higher current rate (e.g. 100A)? SPD is for nuisance trip prevention during raining season and proctect my computer stuffs. Correct me if my understanding is wrong. This post has been edited by Octopuz: Jun 28 2017, 09:16 AM |
