EQ9685R is the 200A main that comes with the LC - the 150A breaker is part # EQ9683R (if they want to try and find elsewhere) otherwise, they need to replace the whole thing **Q: Can I just reuse the lugs or does this one come with new ones?** A: If it's new in box it should come with lugs and a kit. Ours do. **Q: will this breaker fit panel mc0816b1200ct** A: No this takes an MBK200 https://s3.amazonaws.com/dcc-data-extract/full_jan2019/asset/COMPAS/SpeedFax/SF17-02-038.pdf **Q: Can this replace a 150a main breaker, ite model eq9481? panel is 1980's siemens panel. thanks** A: No. The MBK150 would not work in place of the older design EQ9481 breakers. Unfortunately, there isn't a replacement main breaker kit for the EQ9481. It's suggested to replace the entire load center, or source refurbished EQ9481 via 3rd party. ## Customer Reviews ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Perfect *by P***Z on Reviewed in the United States on December 22, 2020* Easy to install, fits perfectly, and you can feel the quality.
