I have a new electric hot water heater that has a green ground to a screw on top, and a red and black wire. The problem is my house is a 30 AMP two pole breaker that has a red, black, white and blue wire!! How do I wire up my heater to all these wires? Hi Mac, From what you have stated the electrical circuit wiring may not be standard, therefore it is in your best interest to have the wiring inspected by a qualified electrician.

The circuit wires should be verified to be correct for your specific water heater having the right type of insulation and the right wire size. The circuit wires will need to be identified at the electrical panel, and the connected wires to the circuit breaker. The bare ground wire is typically the ground wire which should also be checked and verified at the electrical panel for proper bonding to the ground system.

Once the circuit wiring has been verified the connections to the water heater can be performed. Your local qualified electrician will assist you to do it right, Dave. The water heater has black, red, blue, and yellow wires. How can I connect 10 Gauge circuit wire with the water heater. How to connect 3 wire cable with 4 wire water heater. Hi Sam, Please note that the article you have posted your question to is about volt watt Residential Electric Water Heaters.

The water heater you have described is a Rheem Commercial size unit that is watts, therefore the electrical circuit requirements are much larger and the 10 gauge circuit you have described which cannot be used for this unit. Please note that commercial water heaters have different wiring configurations that will apply to commercial buildings with electrical service that are typically different from the average American home. Please consult the installation manual that came with your water heater for more information and wiring options.

The following may assist you as well: I removed a hot water heater that was 12 years old. It was wired from the panel with just 2 red v I assume they are inside flexible conduit. Will I need to have an electrician rewire that circuit with wiring that includes a neutral? Hi Vicki, It depends on what you would like to do with the circuit. If you wish to install a replacement water heater then you will not need a neutral wire, however the circuit should have a ground wire installed.

I hope this helps, Dave. Is there any way to loosen the outer shell? Hi Jeff, With the power off, use the existing wire to feed through the new wire by simply attaching them to each other and wrapping them with electrical tape. Thanks for sharing your water heater question with us, Dave. Why would an electric water heater have a from a 30amp breaker to the heater, then have a separate going from the heater out to the meter.

This is a leased heater from the electric company and is in a apartment. Hi Randy, Since this is a leased water heater that is located inside an apartment it is possible that the additional cable is being used to measure the electrical consumption of the unit at the meter location where a current transformer or other measuring device is installed. I had an electric water heater and replaced it with a gas water heater.

Years later I now am going back to an electric water heater. The previous two ten gauge 2 wire cables are still there. However one of the cables is now hooked up in the control panel box to another 10 gauge cable with wire nuts, and connected with the white wire to white wire, and black wire to black wire, and leads out to my electric meter. Why are the wires connected this way, and what is this for? To make it a live wire again can I just link those wire nut connections to a proper 30 amp breaker?

Hi Curtis, Application: Replacing a gas water heater with a volt 30 amp hot water heater, and reconnecting to an existing volt 30 amp hot water 10 gauge circuit. The original volt 30 amp hot water 10 gauge circuit wires will need to be verified that they are not being used for some other purpose. Once this has been verified the white wires of the original circuit should be colored with red or black electrical tape to indicate that the white wire is not a neutral wire, but is instead being used for one power source of the volt circuit.

The water heater circuit wires both connect to a 2-pole 30 amp volt circuit breaker for proper circuit overload protection. The ground wire is connected to the ground bar of the panel. All the circuit wires should be verified, identified and marked. This verification is essential from the panel location to the water heater location.

I cannot speculate why the original circuit wires have been connected differently at the panel as you have described, and this is why circuit verification is very important, because if the circuit has been converted for a different application or purpose then the original circuit wires cannot be used, and further identification will be necessary. The typical circuit wire connections to the volt water heater is black to black, the red wire of the water heater connects to the white wire which is colored with red or black electrical tape, and the ground wire is fastened and bonded to the ground screw of the water heater.

Hi, I have replaced my water heater. The wiring from the panel is 10 gauge, with three wires red, black and white. My question. I am installing a timer with a manual on and off switch. The diagram for the timer shows where to put the red, black and white wires and a place for the green ground. Should I put the white wire on the ground in the timer and on the water tank? OR should the white wire go where the timer instructions show it should and put the white wire on the ground of the water heater?

OR maybe just tape the white wire off at the heater? Thank you for your time. Hi JoAnn, If the water heater timer requires a Neutral wire then one must be provided along with a separate ground wire. From what you have described the circuit does not have both of these wires. The solution would be to obtain a volt water heater timer that does not require a separate neutral wire. The next important thing would be to have the white wire of the water heater circuit identified at the panel and verified or reconnected to be a ground wire, and marking the wire with green electrical tape at each end for proper identification.

Thank you Dave for your response. I went out to the panel and the white wire is in fact wired to the ground bar with all the other green or white wires coming from the panel. I made the decision not to use the timer at this time. I wired the water heater just like the old one was wired, with the white wire connected to the ground screw. All is good and we have hot water! Again thank you for your answer. I have a hot water heater that I want to remove and replace the wiring with an outlet to utilize the dedicated circuit.

Hi Chris, If you are referring to converting a 30 amp volt circuit to be used as a volt, then yes, this can be done fairly easy. Keep in mind that the circuit wiring will need to be converted to volts at the electric panel, and a new circuit breaker must be installed and sized to the amperage of the receptacle that will be installed, which is typically 15 or 20 amps.

Working in an electrical panel is not recommended for homeowners, so this is best performed by an electrician. I have a Envi-ro-temp Energy Saver model 90a 30 gal. How do I wire it? Name required.
