Plan on pulling a new dedicated 240-V circuit sized to the appliance.

Load-shedding can help you avoid a service/panel upgrade, but it doesn’t replace the required branch circuit.

If your AHJ approves a listed, permanent EMS, fine! but plug-in splitters/DIY controllers rarely pass.

Want to put in an induction cooktop and pass inspection? Installing a 240-volt line is probably your best bet.

Thinking about doing something else, like load-shedding? Make sure you chat with your local electrical inspector or building authority before you install anything.

FYI: Some smaller induction cooktops you plug in use 120V, but they’re more like countertop appliances than a real replacement for your old cooktop.

For induction conversions, the necessity of a new 240-V run depends on the specific electrical setup and local regulations.

  1. Existing Infrastructure: If you’re converting a 3-phase induction motor to run on a single-phase 240V AC supply, you might not need a new 240-V run. Instead, you can use capacitors to create a rotating magnetic field, allowing the motor to operate efficiently.
  2. Capacitor Configuration: The capacitor configuration is crucial in determining the motor’s performance. You’ll need to calculate the inductive reactance of the windings and provide the same amount of capacitive reactance to achieve optimal performance.
  3. Load-Shed Devices: Load-shed devices might not be directly related to the 240-V run requirement. However, if you’re using load-shed devices to manage power consumption, ensure they are compatible with your induction motor setup and comply with local electrical codes.
