How it works
A load management device monitors the current on both connected circuits. When the EV charger is in use, the device reduces or pauses the other appliance. The result: two high-amp loads sharing one circuit without exceeding panel capacity.
What systems network installers carry
- DCC-10 by RVE — most popular. Switches between EV charger and dryer or range. $1,420 installed.
- Tesla Powerwall Gateway — integrated load management for homes with Powerwall + Tesla EV. Higher cost, but tied into broader home energy management.
- NeoCharge Smart Splitter — outlet-level sharing for 14-50 outlet installs. $580 installed; budget option.
- Span Smart Panel — premium whole-home load management with app monitoring. $4,200+ installed; aspirational tier.
When load management makes sense
- You have a 100A or 125A panel and want a Level 2 EV install
- Your other big loads (dryer, range, A/C) aren't used while you charge overnight
- You're not planning further electrification (heat pump, etc.) in the next 5 years
- Panel upgrade cost ($4k+) would push the EV install out of budget
When to do the panel upgrade instead
- You're planning multiple electrification upgrades
- You have two EVs (load management between two chargers + another appliance is complex)
- You want maximum future flexibility
- You're already doing other electrical work — bundling saves $1k+
The network's principle on this: load management is almost always cheaper than a panel upgrade, but it's not "future-proofing." If you're staying in the home long-term and planning multiple electrification upgrades, the panel upgrade is the better investment. Talk through both at the free panel check.
