If no reading, move to circuit breaker box. Similarly, it should be located so as to prevent it from being unduly exposed to moisture. Feel free to leave comments or video responses. If elements did not burn out, then that leaves 1 main suspect: the electricity. It seems that the 20A breaker should protect the 12-2 wiring from overheating. I hope this helps, Dave I had an electric water heater and replaced it with a gas water heater.

Connect bare ground wire to green ground screw. See circuit current requirements in table below. If it hangs up and starts pulling the insulation, pull it back the other way a bit. I confirmed on each broken piece of wire that the resistance was ~infinite; after sanding off the black surface it returned to ~ 0 Ohms. The top element heats until most of the tank is at set temp, then the bottom element kicks on to bring the lower colder water up to temp.

The ground wire is attached to the green ground screw which is in the same wiring junction box compartment which is built into the top of the water heater. Hi JerryR, I mentioned that a voltage drop assuming all connections are good is probably not the problem since most homes the water heater and breaker panel are near each other. Conduit with proper bushing to protect the conductors must be installed. Locate the wall studs closest to the strap measurement and drill pilot holes. . I visually compared it to a piece of 12-2 that I had. If you put an amp-probe on one leg you will measure full current.

Stand on dry boards and wear dry clothes. The upper element will only provide hot water even with and above it which is very little so when the demand drops it quickly heats the water in the top of the tank. This is because the current drawn through the cable will cause a loss in voltage volt drop over extended lengths of cable. That distance caused the voltage drop due to the resistance of the wire at the long run. With remarkable electronic technology that requires the outstanding Coral heater saves up to 25% in electic bills. So if breaker is 2-pole 240Volt, then check that heater is receiving 240 V across top two screws on upper element. We use different type of electric heater element regarding voltage and regarding element type.

In summary: S1, lower thermostat may have some issue, as the R12 is always ~0 Ohms? Recommended for incoming cold water temperature above 50°F, however it can take lower incoming temperatures down to 40°F by reducing water flowrate This amazing instant water heater is designed for one point of use at a time and it can be connected to the existing hot water piping. Pretty much have to put a clamp on ammeter on the feed to the element to see if its pulling power, and use an ohmmeter to see if its shorted or intact internally. If you have 240 at top two screws, then skip down to step 6. For showers rated at 10. On thing more the below water heater thermostat is different then double element thermostat. Enjoy your electric water heater. To make it a live wire again can I just link those wire nut connections to a proper 30 amp breaker? If block covers the studs, use a masonry bit to create a pilot hole.

The thermostat switch have two connection point just lick a bulb socket or holder. You can regulate the temperate form the thermostat switch, i shown the diagram of this types water heater element. I would love to see the old wire you pull out. Here i a shown a electric water heater geyser, in which two heater element instill upper and lower. This metal capping should be carefully, but firmly secured to the wall to ensure the cable is protected before you plaster over it and then install the shower cubicle etc.

The rule of thumb is to size the circuit breaker for the smallest size wire type within the circuit, or as indicated on the equipment label or as instructed in the installation manual. 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. I was able to carefully pull the new wire 12ga per suggestions above using a straightened coat hanger. I do not understand how this wire break for the lower element might happen, as the wire is physically secured underneath the tank insulation, only think I can think of is the wire burned out somehow?

Q2: Upper terminal 4a should connect directly to the upper element dark green wire, confirmed ~0 Ohm as expected and lower element red wire, confirmed infinite resistance, which is not expected , correct? As above the maximum current draw is 18. Check local building codes before you get started to ensure compliance. There should be a main Earth bond linking your consumer unit earth terminal or the main earth terminal of the supply to both your Gas and water supplies, these bonds should be within 600mm of the consumer side of meter or stopcock.

Do 30 minute troubleshoot: Add a comment for more free help. You can install an expansion tank using push-fit fittings. It could be 220 volt, therefore, the current draw will be less that means lower power and less heat but you'll never notice the performance difference To be sure put a voltmeter in a wall outlet and measure the voltage, it be anywhere from 110 volt to 125 volt. Feel free to post questions and comment on others posts. Here you'll read your 220 sort of speak voltage. The water heater circuit wires both connect to a 2-pole 30 amp 240 volt circuit breaker for proper circuit overload protection.
