ENERGY MANAGEMENT: EM-20

Product Description

EM-20

The EM-20 is a cost-efficient, energy management branch circuit expander. This product is designed to share the power from a single branch circuit between two mid-to-large power loads that normally require their own breaker. Potential applications include microwaves, fireplaces, hairdryers, water heaters, or even two air conditioners. RVs with two or more air conditioners frequently require 50A AC service; however, the EM-20 can be employed to manage two air conditioners in an RV with 30A service.

All WFCO products are designed to better meet the needs of RV owners while also making the job simpler for the installer. The EM-20 offers three flexible mounting options, as well as, a number of unique features – like four basic power modes and a remote panel for manual energy management – making it easy for RV owners to assign energy to the circuit they need at any particular time.
