Today I fitted a Sterling 1600 watt pure sine inverter with RCD flex outlet for Norman (awaiting @Jim to change his user name) After completing the installation with a manual changeover switch to service nearly all the sockets, we found the plug in tester was indicating reverse polarity.
After breaking it down the fault was pinpointed to the flex from the inverter RCD which was 230 volts N to earth and zero volts L to earth. One might argue that it doesn't really matter as it is RCD protected anyway BUT it is clearly not acceptable from a top brand product like this.
Rather than the chore of Norman sending it back I just swapped the cores to correct it.
