Explain the benefits of the new generator-ready loadcenters.
What will be an ideal response?
These new loadcenters are only slightly more expensive than standard loadcenters but can save the homeowner thousands of dollars in future generator installation expense. The loadcenter is provided with two interiors, both being powered by the utility power supply. Critical circuits are placed in the lower interior, which is backed up by a generator in the event of a power outage. Providing back up to only the critical circuits in a house reduces the size and expense of the generator required.
