Geoff:
Looks like MyEnergi (and others) are using software/microelectronics based devices for the RCD functions. Is this approach explicitly permitted in the Wiring Regs, or merely "not forbidden" or what? Maybe a "fly by wire" RCD is permitted in the charger provided it is backed up by an electromechanical device on the supply side?
Still new to the Wiring Regs, so if anyone could point to the relevant paragraph numbers it would be much appreciated!
When push comes to shove, isn't a "real" RCD "software/microelectronics based"?
John Peckham:
Out of interest are Zappi claiming compliance with BS EN 61008 for their electronic units in the Declaration of Conformity? I will be very surprised if an electronic device will meet all the requirements of BS EN 61008.
If not you will need a separate BS EN 61008 Type A device upstream to comply with BS 7671 61008.
So it would appear not John. The declaration of conformity doesn’t mention 61008. How would it be permitted to claim compliance with a standard in the technical literature of a product when it is not? It matters not to me as there is always an upstream RCD installed but the Zappi is sold with the advantage of not needing a separate RCD.
what particular elements of 61008 do you think might be lacking?
