For the money they are spot on ......................
most boards have MS on the right. only one i've seen with it on the left is MK.
It’s a 100 ma time delayWhy is the up front RCD not time delayed?
Yea it’s a tt systemAgree with torque settings for screws.
Also I hate the main switch isolator on the right, much prefer left.
Anyone know why some boards have the main switch on the right?
Is it a TT system?
Just curious.
Yes that was exactly my point. Neutral earth fault and the RCBO will trip but the upfront RCD, time delayed or not will still trip as the RCBO's don't break the neutral.@Leesparkykent its a time delayed one so "should" be ok, you can just see the S on the front of it.... The rcbos are only single pole though so there still isnt perfect discrimination and a fault remaining on the neutral will trip the whole supply... Not a great setup imo...
Agree,could be a problem there@Leesparkykent its a time delayed one so "should" be ok, you can just see the S on the front of it....

Do you have the pozi-flat hybrid type driver in your torque set? I do and have never had an issue with the Lewden RCBOsMy issue with the Lewden boards is the advised torque settings, I have two torque drivers and with either if I torque them to manufacturers settings it has a tendency to damage the rcbo screws.
How is fault protection provided for the 63A circuit ?
I thought it was time delayed ? How will this meet disconnection times ?By the upfront rcd....
Hi - TT disconnection times for a distribution circuit is up to 1 second from Reg 411.3.2.4I thought it was time delayed ? How will this meet disconnection times ?
Bear with me as I have nothing to do with TT systems and probably lack a lot of knowledge in this area.
Cheers for that. Thought I would be missing something. Didn't think the higher times applied to TT.Hi - TT disconnection times for a distribution circuit is up to 1 second from Reg 411.3.2.4
