Installing EVSE with a Shunt Trip.

Sparkingchip

Are there any circumstances where installing a Shunt Trip upfront of EVSE is a requirement, rather than just being an optional upgrade?

    Not sure what you have in mind. I've seen shunt tips in a few odd places - most recently on camp site electric hookups where they were used as an alternative to interlocked sockets - there must have been a microswitch or similar on the socket as pulling the plug tripped the shunt release so the MCB/RCBO had to be reset manually after the plug had been re-inserted.

    Having to manually reset a protective device is a bit tedious in general though, and it's hard to think of a situation where that would be preferred over letting the charge point itself do the switching. Maybe if some system detected some 'abstraction' through the charge point and wanted a hard shut-off. Open-pen detection and the like would need to open PE as well, so tripping normal protective devices wouldn't be the way to go.
