Customer Question

I'm ***** *****. Have Rheem RTE 27 tankless water heater and have proper wire gauges/breakers for two 60 amp circuits supplying it. My only concern is that I have spaced the two breakers properly to provide 3-phase operation. On the same side of the ITE service panel there are two 110 volt breakers vertically separating the two 220 volt breakers supplying the two RTE27 circuits. Is that good? Can supply photo. Thanks.
JA: Thanks. Can you give me any more details about your issue?
Customer: RTE27 worked OK for 2 years then quit. Home Depot has refunded full value of heater and I plan to get another due to the convenience of the wiring and plumbing being in place and ready. I wired it originally without deep analysis of the 3 phase question (have done a lot of wiring, no 3 phase). It worked before...but has occurred to me that I may have sacrificed energy efficiency by possibly not taking advantage of 3-phase configuration (wanted to be sure before installing the new RTE27).
JA: OK got it. Last thing — Electricians generally expect a deposit of about $18 to help with your type of question (you only pay if satisfied). Now I'm going to take you to a page to place a secure deposit with JustAnswer. Don't worry, this chat is saved. After that, we will finish helping you.
