Mike, exactly which AC Outlets/Appliances don't work? My troubleshooting would be:
1. Temporarily bypass EMS
2. Cycle (all the way to Off, then back ON) all AC Circuit Breakers. You may have already done this as midnight suggested.
3. Hunt down any GFCI (Ground Fault Circuit Interrupt) devices (most of these are a wall outlet, and one usually protects several more) and press Test and Reset.
