Load Management lets you install a larger breaker than a traditional load calculation allows. For example, if you have a 100 amp panel that already has 90 amps worth of breakers installed, you would traditionally be limited to adding a 10A breaker. Load Management allows you to install a larger breaker, up to 60A in size that which allows you to charge at 48A. Load Management will monitor the panel’s total energy usage and adjust the EV charger to keep the total current through the panel below 100 amps.

Basically traditional breaker sizing can be applied similarly as if you were installing the EV Charger without Load Management. You'll need 20% additional capacity available on the breaker than the anticipated maximum charge rate supplied by the EV Charger.

Here's a handy list of typical breaker sizes and their related available max charge rates:
