How much panel space does the HOM245 require?
As a 2-pole Homeline breaker, it requires two standard 1-inch spaces, taking up a total of 2 inches in the panel.
What is the recommended terminal tightening torque for the HOM245?
The box lugs on the HOM245 should be torqued to 40.7 lb-in when using 8 to 2 AWG copper or aluminum wire.
