The pictured energy monitor is designed to be installed inside a load center. I want to install it outside, on the wall next to the load center. I have not shown all the signal wires that plug into its sides and top. They can all easily run through a knockout with a suitable grommet. The issue is the power wires, shown in the picture. They are at line voltage. My question is what's a good way to install this outside the load center, with appropriate protection and routing for the power wires through a knockout?
I could run them loose, as shown, through a knockout with a grommet but it seems like more protection is appropriate.
I could encase them in heat shrink for a little added protection, but not much. No strain relief that way.
I could use 1/2" conduit butt up against the bottom of the device through one knockout, and run the signal wires loose through a second knockout.
I could use flat cable raceway, and run the power AND the signal wires all through it but that would have no clean interface to the load center knockout and it would probably be a red flag to any future inspectors/surveyors to have raceway used that way.
I expect some to say "use it as designed". I appreciate that. The question is, what's a good way to mount it outside the panel?
Why do I want to install it outside the load center? Because the things I want to monitor are in FOUR different boxes. I have 300A service coming into a splitter box feeding TWO panels, all mounted on a wall in a row. I also have a generator feed coming into a transfer switch. I want the main service sensors on the 300A service in the splitter box, I want various load sensors in both of the two load centers, and I want a pair of sensors in the junction box feeding INTO the transfer switch. It's MUCH MUCH easier to achieve all this if the monitor is outside any box. The only "issue" I'm grappling with is getting power safely to the monitor, given is fed directly with these flimsy 240V loose wires.
In view of the excellent answers and advice provided so far I’m adding photos to show part of the problem, and my intended solution.
Almost all the sensors are in the 200A panel so it makes sense to have the Vue NEAR this panel. I could put it inside the 100A panel, easily, but then I would need extension cables for 13 sensor channels. I could put it inside the 200A panel but there just isn’t room … everything that’s already in there, plus the device itself, and all the excess cable, and there are also 6 more channels coming from nearby boxes that then would need to route into this panel adding to the crowding.
Please correct me if I’m wrong, but I think putting everything inside this panel would be the wrong approach. I could trim all the cables from the transfer switch to regain space but then I'll lose flexibility to move them to different breakers in future.
So I plan to add a new box with new conduit to three boxes. The two 200A utility sensors will be in the splitter box on the right, routed through the the 100A panel's existing conduit. I haven't decided if to use a metal or plastic box. I'm grateful for the advice on why not to leave it all outside.
