ThinkGrow 3' 20A AWG#12 Extension Power Cords

ThinkGrow DEA-12 3 ft 20A AWG#12 Extension Power Cord Step up from the 15A DEA-14 to the DEA-12 when a daisy chain needs to carry 20A continuous. The cord runs 12 AWG copper (3.31 mm2). The 3 ft (0.9 m) length is the same tight fixture-to-fixture jumper as the DEA-14. The larger conductor lets a single chain hold five or six full-power Model-H fixtures on a single 277V circuit instead of three or four. ETL-listed with IP67 connectors. When 12 AWG Beats 14 AWG in the Same Room On a 20A breaker the DEA-12 uses every amp the breaker is rated for. The DEA-14 caps the chain at 15A regardless of breaker size. Voltage drop across 12 AWG over a 3 ft jumper is effectively zero. Every fixture on the chain sees the same input voltage even at full current. Growers typically pick the DEA-12 when fixture count per circuit is the bottleneck rather than total room power. Key Features Length: 3 ft (0.9 m), the close jumper between adjacent fixtures Wire gauge: 12 AWG copper, 3.31 mm2 — sized for 20A continuous duty Amperage: 20A — one step up from the 15A DEA-14, lets more fixtures share the same breaker Voltage range: 100-277V auto-sensing, matches the ThinkGrow ecosystem Certification: ETL-listed and IP67 waterproof connectors Technical Specifications Specification Value Model DEA-12 Length 3 ft (0.9 m) Wire Gauge 12 AWG (3.31 mm2) Amperage 20A Voltage Range 100-277V auto-sensing Certification ETL-listed, IP67 waterproof connectors Compatibility ThinkGrow Model-I, Model-I Plus, Model-H, Model-H Plus, Model-V, Model-W
