That's certainly not the three year warrantee that AeroVironment gives with the installation, but that would be pretty good if we had a different licensed electrician install it. Does anyone know if that one year warrantee is correct for the UL stamp?
Danny - I'm not going to speak to the UL stamp, but the warranty in general.
AV provides a warranty on the EVSE. That cannot change regardless of who installs the EVSE.
As I see it, here's the warranty break-down. If an AV rep or contractor runs a wire from a breaker box to the EVSE location, and then connects the EVSE, there are multiple warranties in play - they all go back to the manufacturer. If new breakers are installed, the breaker manufacturer carries that warranty. The company that makes the wire owns that one, the folks that make the staples or conduit or electrical box owns those warranties. The electrician that installs everything can offer an ADDITIONAL warranty on the hardware if they wish, but their warranty could only be limited to their work.
AV is still on the hook for the EVSE warranty regardless of who installs it (unless they have a prohibition on unqualified homeowner installs, I guess...).
If I choose to install the wiring to the EVSE connect point, then by default I accept responsibility for going back to the Romex, conduit, or circuit breaker manufacture (or Lowes!) for warranty replacement if one of those parts fails.
If I choose to welcome an electrician (or an AV installer) into my garage and simply grunt and point, then the installer is 'on the hook' to chase down warranty service if necessary (while we drink coffee).
Having another electrician install the AV unit doesn't remove AV from their warranty responsibility - and doesn't remove the electrician's responsibility from her work, or Square-D's responsibility for the breaker.
