We just purchased the same model and it has one tiny ground screw. I'm guessing you couple the two ground wires and fasten the one to the screw.... 240 volts just guess right?

Thank u so much

Tnx for the nice video. I'm from kingdom of bahrain. I have same heater. I make same connection 2 *40 Amp fuse control but neutral share not double pole. I mean neutral direct to busbar. I heard noise in fuse while it is heating the water?

If I am not mistaken, By code you need an electrical cutoff in site of the unit if it's not near the breaker box. I have seen these cutoffs on things like AC units. What cutoff product do you buy when you have two circuits going in and out?

On mine The white and black wires are set up in reverse to what you have pictured here .. I didn’t install it. It was here when I moved in. We just had a power outage of course and it killed the control board I think. No hot water.

Where did you get the fittings? Are they 3/4 both ways for yours?

So our home power is 220 volts not 240. So what would be wrong with using a 30 amp breaker and 10 Guage wire?

How's it working? I'm interested in installing one. Just need know it keeps water hot

What causes the lights to flicker while the hot water is in use? It's currently 21° outside and my indoor unit won't heat any water, is there a fix for this?

Hey Preston636 how far away is your breakerbox from your heater? TIA.

do you have 240v there or less?

What about wiring for 13kw? Can you do that?

For the equipment ground, why do you need two wires? Also why not use green insulated wire instead of bare copper, especially for long feeds.

I'd go with 8/3. It has a red hot, black hot, white neutral and bare ground.

The only problem with 8/2 Romex is the ground wire pulls double duty both as a neutral and equipment ground, you might want to tag the white with black or red tape to identify it as a hot in the heater as well as in the panel

Just like your video, there's a white, black and ground. You don't have a neutral either. Both white and black are hot? Do you not need a neutral or is the white neutral but hooked up to the breaker? All my other wires in the breaker have a neutral that's grounded like a ground. I'm confused. Thanks for the help!

@@drmoynihan Higher current devices should always be near where the mains are coming in from the street. The reason being is a voltage drop will be created over the busbar in your panel and that drop will appear on other branch circuits. By having the breakers near the feed the voltage drop will be less and you'll see less of this drop on other devices. Also you'll get more power to the device being powered that wants the higher currents. Good electricians always wire panels with the high current loads near the feed. Bad ones, they don't know and/or care. I'm running the Rheem 18 and so far so good.

What is E5 code ?

So is the voltage across each of the lugs supposed to be 120v or 240v? I thought the voltage across L1 & L2 should be 120v, but Rheem is telling me it should be 240v. The person on the phone seems like she was reading straight off the documentation though. I am getting an error code of H103, the Rheem tech support is saying that is a voltage problem. I started with the smaller model, RTEX-13 and upgraded to the RTEX-18, the RTEX-13 required 6 gauge wire and it had a red wire for 240v and it was on a 60AMP breaker (two 30 AMP poles). So when I swapped it out for the RTEX-18 the electrician said I can connect L1 to the load, and L2 to the neutral and on the other set, I could use the red wire from and the ground wire since the ground and neutral were on the same bus. So that yields 120v across L1 & L2. Is that right, or should it be 240 across L1 & L2? I hate to eat a $400 mistake.

@drmoynihan

You have 2 120v power lines, plus a ground, coming into your house, which added together equal 240v. 120v goes down one side of your box and the other 120v goes down the other side. When you have two 120v breakers connected as twins, each is hooked up to the opposite side, which combined together give you 240v. If you do not understand this, you should really hire an electrician or at least a friend who understands. 240volts is really dangerous!!!
