EV chargers and double pole RCD's.

[goasis]

So regulation 722.531.3.1 says RCD's shall disconnect all live conductors.
Is this requirement met if the charger itself contains a DP RCD? As presumably there is no reason that the installed circuit requires a DP RCD? in fact depending on cable type and install methods the cable may not need an RCD at all?

The Zappi actually requires no RCD upstream (as it has internal Type A + 30mA DC). So - if your supply cable is compliant (SWA/protected/not concealed) you could just use an MCB (32A for a Zappi, but you DO need a 2-pole isolator switch in-circuit).

Actually this is not the case, as can be read in this excerpt from the MyEnergi website:

"It is important to note that the standards for EV charge point installation usually require an RCD which meets a specific standard – IEC 61008 for an RCD or IEC 61009 for an RCBO. The RCD in zappi does not fully meet these requirements which means that a separate RCD or RCBO to these specific standards needs to be installed."
