Leviton MO240-1SW Outdoor Surface Mount Mechanical Counter 120/208/240V 2P3W 100A with 2 Solid Core CTs Mini Meter Kit

this device seems to be working very well i have no real way of knowing its accuracy however it seems correct for the appliances and lights that are being monitored. i am a homeowner who did this not a certified electrician and the reason i gave it four stars instead of five is that i found the instructions so typical of manufacturers instructions done by someone who may possibly understand all the factors but fails to write them for someone less educated on the subject.. its like dont you ever ask someone who has never installed your product what questions they might have? the answer is obviously not. i searched the web and found other manufactures who had written much better instructions for similar products and I simply had to guess at the rest. I might mention that i talked to two professional electricians who had never seen or heard of such a device let alone installed one which made me realize how ignorant Leviton is of their potential installers and the information they might require for a successful installation.

What a great productThe employees of Amazon should not be afraid to start a union.

I added this above my sub panel to keep track of the power my detached garage uses and it seems to be accurate. Only criticism I have was not having a clean way to mount the meter on the wall or flush given heaving to run flex pipe to connect from the sub panel to the meter box. The area to pass the wires didn’t give a great option.

Got this to measure usage at a sub panel. Be prepared to drill a hole or 2 to get the wires where they need to go. I'm not sure why they couldn't mold knockout plugs like many others do. I found something cheaper and easier to install. Never used it so I can't rate the accuracy. I'm sure it will be fine.

Excellent product. I am a electrician. So that helped with the install.

Just as advertized, after four months, accurate as I can tell. Easy to install, but read the directions first!

We put this into the main breaker panel in an office trailer that's permanently anchored next to our industrial warehouse. The whole property is on one meter, so until I installed this, I couldn't bill the warehouse tenant because I didn't know how much electricity the office trailer was using. Now I can collect for the electricity used by the trailer tenant, and credit the warehouse tenant.

I'm a master electrician and installed this submeter. It has exceeded my clients expectations.

The product itself is great. But there is only installation manual included, no user manual. I have to search on internet to download it.
