What to plan for in Mount Pleasant
- Coastal flooding (very high): Coastal flooding means keeping batteries, generators and electrical panels above flood level; ask a licensed electrician about elevating equipment.
- Hurricanes (very high): Hurricanes can mean a week without power. A standby generator on natural gas or propane, or a battery with solar, beats a stack of gas cans; check flood height before you site equipment.
- Earthquakes (relatively high): Earthquake risk is mainly about secure mounting and gas shut-off for generators; ask the installer to follow local seismic requirements.
