I’d also run the baseboard heater wires to the same junction box, by running one 12/2 cable to the 2 heaters and connecting them in parallel, not serial. . in which case you will need to measure the resistance of the heater and do some math. . That confirms what I was reading. The system was previously inspected by a licensed electrician . In order to find the resistance of the heater element from the above described section, we must algebraically modify the formula to read (r = v/a). Since we know that the hot water electrical circuit feeds 220 VAC to the 16 ampere heating element the resistance of that element is equal to 13.75 ohms. We can round that number up to 14 ohms.As a home inspector with 7 years experience, I have 4 action items from this single picture: inadequate clearance to electrical panel, water heater vent pipe is flexible, water heater TPR discharge pipe is missing, spray foam sealant around the vent pipe is unprofessional. 30A is correct for a 40 gal water heater. Putting a 30A breaker in a 30A breaker box is not WORSE than a 30A breaker in a 60A breaker box. The load is on the breaker itself, NOT the box. If the water heater is the only thing for this breaker box, it only needs to match the intended breaker of 30A.
Listening closely, I heard a faint humming from the water heater. Half hour later, I checked a tap and got hot water. I tried to find the junction box. According to the manual's drawing, it looks like it's on the side of the water heater, which is below floor level in the MH. From below, it's above the floor of the storage bays.

I am remodeling a house and plan on installing a on demand water heater. The one I am looking at requires 3 - 40amp breakers. How is everyone wiring these in? 1. Mounting a junction box on the wall and then going to the water heater with 8/3 Romex in the open? 2. Mounting a junction box and then conduit to the heater? 3. Conduit from breaker .
Found a junction box in the crawl space that had 240v to it, so I knew the problem was between there and the water heater. Finally, I opened up the junction box in the wall behind the water heater to find there had been a fire and one of the wires from the box to the heater had burned.(yet I still had 120v to both wires) I removed wire nuts . Unless your picture is not showing us everything, you do NOT have two ground wires! In this picture, the ground wire is pointed at by the green arrow. The bare piece of wire that I think you're seeing as another ground wire (pointed at by the red arrows) is actually (most likely) then Neutral wire, note the white insulation hiding further back in the box. I would pause when I was near the offending box, and light everything back up. Then, having a voltmeter, I would set it on AC volts and measure between the almost-there ground wire and the offending junction box. A voltage reading indicates a ground fault in a circuit using the box**. We have instances of where the water heater isn't plugged into an outlet behind the water heater.thus no power. Here is a pic of the 120 volt AC hi-limit thermostat (on the left side, as the right one is to the 12 volt DC), with the fusible link burned out between the hi-limit and thermostat..which won't allow power to the electric element.

Rarely, some small 30-gal heaters will be rated 3800 watts which works out to a 20-amp circuit, but most water heaters in U.S. homes are on 30-amp circuits. 30-amps circuits require a 30-amp breaker and number 10 gauge cable. Also note that electric water heaters are sometimes advertised as having dual 4500/4500 heating elements. The line currents we are reading for each heater are 1.7A which makes sense for the overall 1460W heater rating I would then expect the current across each heater element to be 1.7A / 1.73 = 1.0A. With all that said taking the 480V L-L across each coil and dividing it by the measured impedance of 260ohm gives a current across the element of 1 . Any water heater installed with a power cord like a dyer cord must be changed to direct wire when the WH is replaced. Most water heaters are wired with 10 gauge wire and the breaker is 30 Amps. Older homes, before 1980's may be 20 amp breaker with 12 gauge wire.
