When using a 2-wire Romex cable with a ground understand that a 2-pole circuit breaker will be required and the white wire will need to be identified with red or black electrical tape as a power conductor at both ends of the circuit. I always used a double pole breaker and use a 12-3 wire to get 240v. Romex is going to the next heater, the other is coming from the wall thermostat. Connect each hot wire from 240Volt breaker to either one of the screw terminals. My current county building dept requires 10 with the breaker to be 25 amp. Sounds like this is a fairly new electric water heater. Some sort of short or leakage to earth or something? Also, look for broken light sockets or other damage that may be causing the device to short when plugged in.
People think the get shocked with 240v, when in reality they are hit with 120v. Plumbing the Water Heater Begin connecting the plumbing to the water heater by connecting the cold water feed to the cold water inlet on the heater, then connect the hot water outlet to the hot water side -- usually the left side -- of the faucets. Again, if only the wire nuts are hot, then you've got a problem. Add the cost of money over those 20 years, and you could figure it to be 25 years worth of time for any payback. Following this handy guide will ensure great results: Watts Coverage Area Square Feet 1000 100 1,500 150 2,000 200 2,500 250 3,000 300 3,500 350 4,000 400 It's important to remember that the square footage listed in the chart above is a general guideline for determining your garage heater you need. Connect bare ground wire to green ground screw. Then, when you install the garage heaters, place them strategically in the space you are trying to heat.
Apparently when installing, i duplicated the original wiring by connecting the black wires to the water heater's red and black with caps, which seems reasonable. The other leg always has power. If necessary, run a new circuit to serve the need of all your appliances. It may be a good idea to find out why the ceiling heating unit is not working before proceeding with a new wall heater. If it is wire in conduit or some other type of raceway, white and grey wire are not permitted to be used for an equipment ground - re-marking or not. Plus, it will save you money and make your garage heater more efficient. For a price, fixya expert speaks with you over phone while you work on timer.
Again, just like your flashlight, the center tap, or neutral, wont really matter. Thanks for any help, Tom I forgot to add this bit of information. Also take advantage of fixya phone service. Heaters come in two types: 120-volt or 240-volt. If all appliances are in good working order and the circuit breaker continues to trip, there are too many appliances, lamps. All splices and joints and the free ends of conductors shall be covered with an insulation equivalent to that of the conductors or with an insulating device identified for the purpose.
Modern tank units are very well insulated and don't have much heat loss when idle. I have no issue with the switch. It can be one black and one white as no neutral is needed for baseboard heat. This would be a dedicated circuit that is used only for the heater s and not other 240-volt appliances. The person who did the original wiring was probably as much an amateur as me. Ours is a natural gas unit, I think around 2008 model. Do i than connect the other hot wire red directly to the heater?? My current Local code requires 10 wire and 25 amp breaker A 4500 watt element draws 18.
Should i pound a grounding rod into the dirt directly below the floor and ground it that way? If you put an amp-probe on one leg you will measure full current. Either a properly installed floor drain or the sink drain will work. By following a few simple instructions you can safely install this heating method in short time. I discovered well after I already bought them for a basement finishing project that they require double pole Thermostats for 240V heaters. More information at the website.
Are you testing voltage across top two screws on element. If it was you would feel heat off the wires that is feeding the water heater. At 2 gallons per minute standard for a shower he will need anywhere from 14. Then place the voltmeter across the upper thermostat of the water heater. However the correct fix is to buy that 10 cable that you need for the water heater with a proper ground wire. Or your switch is not sending power alternately as called for to the elements. Especially if you do not keep the water temperature low unhealthy.
The only thing, but not necessary, is to consider changing out your breakers to 20 amps so that way if your motor for some reason starts to pull more than the amps the outlet is rated for your don't melt the outlet or have a fire. I use 6 gauge wire with 50 amp breaker. Often inside main panels you find neutral and ground wires connected to the same bus bars which probably goes against good workmanship rules. This wiring is for a 30 amp circuit breaker serving a 30 amp, 240 volt receptacle. It may be asking for more but it just isn't available? Which should it be and should i correct it? They're designed to withstand the highest abuse and resist impact and cracking. As above the maximum current draw is 18. Still can't figure that one out.
