Sarmajor, what is your opinion on the situation where a 24VDC power supply is connected to the 230VAC supply via a 3 pin plug and switched outlet? The 27.5VDC output is then connected in parallel with the house batteries, providing a little top-up to the batteries whenever connected to mains power.
Is this likely to cause any serious risk in the event that a fault or internal short may develop within the power supply device? Presumably the two systems could be termed "associated" in this case? Does this fall within the EWOF system?
Would the RCD and/or overload protection on the incoming mains supply provide sufficient protection? Is there any possibility that mains voltage could anyhow become interconnected to the 24V house wiring?
