- Security systems
Whole House Backup
What is whole house backup? It means your generator powers every circuit in your house. You do not have to choose which things get power. Your whole house works like normal during an outage.
You put the ATS close to the main electrical panel. This spot lets the switch control all the power for your house. You need a generator that can handle all your power needs.
| Whole House Backup | Essential Loads Only |
|---|---|
| Powers all circuits | Powers select circuits |
| Needs large generator | Needs smaller generator |
Note: Whole house backup is easy and comfortable, but it costs more.
Multiple Services
What if your property has more than one electrical service? You might have a main house and a garage or a workshop with its own panel. Each service needs its own ATS.
You put an ATS at each service entrance. This keeps each building safe and powered during an outage. You must pick the right size generator and ATS for each service.
- You keep each area safe from too much power.
- You make backup power work for different needs.
Always check local codes when you put more than one ATS on your property.
