Use this power chord to connect your EcoFlow Delta Dual Voltage Hub to your Smart Home Panel. 

Whole-home backup power: Connect your transfer switch/power inlet box and double voltage hub with an L14-30R to L14-30P generator cord to keep essential circuits running. This cord is available with the Advanced Kit (2 x DELTA Pros + Double Voltage Hub).

Partial home backup power: If you're using the Starter Kit (single DELTA Pro), you will need an additional TT30P to L14-30R adapter to connect it with the L14-30R to L14-30P generator cord. Afterward, directly connect the DELTA Pro and transfer switch with the generator cord.
