Review on Leviton 51110 1: Ultimate Protection for Commercial and Residential Spaces by Ted Higdem

This unit mounts to any electrical panel with minimal effort, no 7/8" knockout hole and no 7" space on the knockout side. It has good performance and this device protects your home from fast power surges and power surges. If you are not very familiar with electricity and panel wiring, it is best to leave it to a qualified electrician. If you are good at it, install it according to the drawings that come with the product and have peace of mind. This product is a sensible alternative to many individual surge arresters.
