Hey everyone! I'm in the process of planning for a new induction range and I'm trying to figure out if I need to upgrade my electrical service and panel to support it. Here's a bit of background: my home currently has a 100A service and a 100A rated panel. The new range requires a 14-50 outlet with a 40A feed. The only large load I have right now is an EV charger, which is set to max 32A. I mostly have typical household loads (lights, outlets, etc.) and I don't use the range and charge the EV at the same time, so I'm wondering: 1. Does the NEC require an upgrade to my service or panel because of this setup? 2. What should I consider for sizing my panel and service? 3. Is there a smart way to ensure the range and EV charger aren't used simultaneously? Any advice or references would be greatly appreciated!

An electrician can perform a load calculation based on your home's setup, which will clarify whether an upgrade is necessary. Generally, with your current load of 32A for the EV charger and 40A for the range, it's pushing your limit, especially if you consider the additional small appliance circuits. Before making a decision, definitely consult a pro to get the right calculations done!
You will likely need an upgrade since a typical 100A service might not handle the combined loads well. The National Electrical Code (NEC) intends for future-proofing, which means it's safer and often required to have more capacity. It's also important to check if you have enough slots for adding a 40A breaker. If you're not on the maximum edge yet, you might manage for a while, but it’s better to opt for a smoother experience and upgrade to 200A service if possible.
True, system upgrades can offer more flexibility. Even if everything seems fine now, future needs can sneak up on you. Better to have the capacity than to be stuck later!
