Using AdaptersUpdated 15 days ago
NEMA adapters allow you to connect devices with different plug types to your Smart Splitter safely. Here's what you need to know about using adapters correctly:
Safe Adapter Usage: The Smart Splitter's input and output receptacles must match your wall outlet type due to UL safety certification requirements. When your EV charger has a different plug type than your wall outlet, use an appropriate adapter to make the connection compatible.
Correct Adapter Configuration:
NEVER connect an adapter between your wall outlet and Smart Splitter. Instead, use one of these safe configurations:
- Wall outlet → Smart Splitter → adapter → EV charger
- Wall outlet → Smart Splitter → EV charger (when plugs match)
Example Setup: If you have a NEMA 10-30 dryer outlet and an EV charger with a NEMA 14-50 plug:
1. Purchase a NEMA 10-30 Smart Splitter (matches wall outlet)
2. Use a NEMA 10-30 to NEMA 14-50 adapter to connect your EV charger
3. Plug your dryer directly into the Primary outlet
4. Connect your adapted EV charger to the Secondary outlet

Important Considerations:
- Always verify your EV charger can adjust to the appropriate amperage for your circuit
- For 30A circuits, ensure charging is limited to 24A or less
- Some EV brands have specific adapter requirements (refer to manufacturer guidelines)
