Mercedes-Benz GLC 350e is a plug-in hybrid, and it comes with no charging cable as time of writing this article.
It can charge at 3.8KW with a level 2 charging cable, which is about 16amps on 240V.
Thus customer who needs a splitter switch can purchase either SPS 01-011 or SPS 02-022 depending on their home circuit configuration. Then buy any 24 amps charging cable aka EVSE to charge their car.
