Hello everyone,
I’m in the process of installing multiple Shelly Pro 1 units in a building and could use some expert advice. My primary objective is to ensure that, in the event of a failure or any issue, there’s an easy way for anyone to bypass the Shelly system. This is important to avoid the necessity of my immediate presence for troubleshooting.
I’m considering a setup that involves double circuit breakers, with one serving as a bypass. Does anyone have experience or insights on whether this is a viable option? I’m particularly interested in solutions that are straightforward and manageable even for those without technical expertise.
Any suggestions, tips, or recommendations on this setup or any alternative methods for an effective bypass system would be highly appreciated. I’m looking forward to your valuable input!
Thank you in advance!
On Quick look, don’t see why that wouldn’t work. so you would be using the backup circuit breaker as a connection switch…
The only downside is if the Shelly relay does turn ON, and you have manually turned on the Secondary then you have two 16A breakers for the load (not one). That could be remedied if you used a double throw contactor relay to isolate the circuits and the bypass not just powers the relay, but also triggers the relay (disconnecting the primary breaker).
