I attended this Zoom webinar on How to Avoid Electrical panel upgrades when moving to an EV charger or adding new electric appliances.
The speaker appeared knowledgeable and covered lots of territory in his talk. The slides are a good overview and can be found here.
The recorded session is available here.
The basic theme was, with modern appliances, e.g. electric water heaters, dryers, EV car chargers, you can avoid having to increase the size of your breaker box to accommodate them.
Older homes usually have 100 Amp breaker capacity, some have 150 Amp. Newer homes have 200 Amp capacity breaker boxes.
Upgrading from a 100-> 150 or 200 Amp breaker box service can be terribly expensive and time consuming, so he offered ways to avoid it.
All the workarounds conform to National Electrical codes.
Best audiences are people thinking about getting an EV but are concerned about charging it and people who want to move to more electrical major appliances to avoid natural gas.
