I give up…
What are peeps using as a breaker on the output side of a Quattro 2x120?
Victron’s wiring guide suggests using an ELCI, but i have yet to find a 3-pole, GFCI or ELCI, 75-100 amp breaker…
Have a look at RS below
'3-pole 100a ’ | RS (rs-online.com)
or this below from Siemens
(3-Pole ground fault breakers - Siemens US) available from Mouser (not cheap tho)
3RV20414MA100DA0 Siemens | Mouser United Kingdom
Not sure if any of these will fit you need, good luck.
