  • 3 phase, 120/240-Volt or 120/208-Volt, 100 Amp main breaker load center with 12-spaces/24-circuits
  • Aluminum bus
  • Ground bar field installed
  • Combination head screws on neutrals, ground, trim, upper pan, and bond screw provide installation flexibility
  • Single side inboard neutral
  • Invertible for bottom feed application
  • All ES series load centers allow the main breaker to be converted to main lug, but not vice versa
  • Mounting tabs on the trim hold it in place on the load center, freeing up both hands to drive the trim screws
  • Pre-positioned bond screw eliminated bond straps/screw assemblies, and reduces the risk of losing components in the field
  • Insta-wire neutral/ground system allows for faster installation because screws arrive backed out, ready for wire insertion, the visible neutral and grounds systems also aids in the insertion of conductors
