Hi all, New member and posting for the first time. I ran into an issue this past Friday, and have been reading through electrical posts and articles for the past few days, but thought I might be able to get some good advice for my exact situation. I recently had a basement remodeled, which included the contractor adding additional wiring and LED lighting. Everything was working as expected for about 2 months until Friday evening, when I came home to a tripped breaker that cannot be reset. It was a rainy evening, which may be a factor. The new wiring included a circuit that runs to 5 indoor recessed LEDs, 2 on one dimmer, 3 on a second dimmer. These are Lutron dimmers, that state something along the lines of "For permanent incand fixtures, 600w max" (ie. incorrect for LED use? The LEDs are dimmable). There is also one new outdoor LED light fixture on a switch. Additionally, there are 8 outlets not working currently, which I believe are all tied together. 1 or 2 of them are new, the others were existing. The house was built about 20 years ago, I have lived here for 3. I have checked behind each outlet/switch cover and do not see any glaring issues. Last item, I initially thought that the circuit breaker was bad. Upon replacing I see that the circuit in question appears to be double tapped. Whether it should be, I do not know. However, the "good" line is fine when hooked up alone. The "bad" will trip immediately when alone. At this point I am reaching out to have an electrician come by, but I'm just wondering if anyone has any advice or ideas about may be going on. I thought maybe water got into the outdoor LED wiring, or if the dimmers aren't intended for LEDs, this may be an issue. However, none of the lights were on when this started, Only 1 outlet was in use for a wifi range extender, which still works fine in working outlets. Any ideas? Thank you in advance!

I need to meter a meter the electricity used in a apartment and another building that comes from a central location, there are spots to put the meters that a meter box can be easily tied into the system but I was wondering if this meter(Landis Gyr RXS4E Electric Meter 4W 3P Cl 20 8S/9S 60hz 1.8kh 120-480V) would work for both applications. My electrician said for the apartment it is a 120/208 volt 3 phase 4 wire and 100 amps, while the other building is pulling 300 amps, would this meter work for both buildings or not, what would you suggest that is cost effective to meter the building and apartment.
