Wire Gauge For Furrion Tankless Water Heater For 40 Foot Distance

Question:

What size gauge wire do I need for a 12v tankless water heater in my Freedom Express RV trailer? It is approximately 40 foot run from battery to heater. Thank you! CD.

Hi CD,

I'm not sure what water heater you have, but for what we offer, the Furrion RV Tankless Water Heater # FR98SR, you'll want 14 gauge wire for the approximately 40 foot distance you mentioned. I would imagine it's the same for most heaters, but you'll want to check the manual, which should specify.
