Wiring concerning distribution board diagram

Hi,
I've been wondering about the breakouts, the power being supplied to them require low currents I believe? My question is that concerning the diagram that First has provided in the readings, It shows that the wires for the breakouts are all diverging from a single wago connector; is this I guess a solution to providing protection to the breakouts since the breakouts require 5A breakers? In other words instead of connecting the breakouts to individual wagos and providing a 5A breaker to each they connected all the breakouts to one wago and attached a 20A breaker? and also would this make sense? I don't know much about electricity and so I'm wondering that the total current required for all 3 connections if it were to exceed 20A than it would disconnect the wiring, in other words providing (20/3)A protection for each individual wire
thanks hope it makes sense
Oh and another thing is we have followed the diagram and so we are wiring it as such and it works. The only concern is if this is allowed and if it does provide the protection needed.

Re: Wiring concerning distribution board diagram

If the wiring diagram shows all of the breakouts receiving power from a single 5A breaker in the PD, then this is PROBABLY going to be acceptable solution per the FIRST rules. It's important, however, to note that many of the datasheets describe such wiring as "typical but the FIRST rules dominate". The real answer should be provided over the next few hours as the game and rules are unveiled.

IF FIRST allows all of the breakouts to receive power as shown and you use a 5A breaker, then it's important that every wire in the bundle be rated to carry 5A (typically at least 22AWG wire).
