What do you want backed up?

🏠 The whole house — everything stays on like normal 🔦 Just the essentials — fridge, water, heat, some lights 🤷 Not sure — recommend for me

What kind of setup are you picturing?

⚡ Automatic standby — kicks on by itself when the power drops 🔌 Portable generator with a hookup — wire in a safe connection for a portable (owned or planned) 🤷 Not sure — show me options

About your home

Square footage (roughly)

Main breaker size

How is your home heated? Do you have natural gas at the house? 🏚️ There's a detached building or second panel with power — barn, garage, shed, pool house

Check what your home has

Check everything that applies. For each one, a photo of the nameplate sticker (the label with the model # and electrical ratings) makes the sizing dead-accurate — but it's always optional.

Anything else big? Optional

A few photos of your setup Optional

📸 If you can, snap: your panel with the door open, a pull-back of the panel area, your outside meter (and gas meter if you have one), and the spot where the generator would sit.
