Hot Water Heater

I have a small 19 gallon water heater in a small garage space, that was installed by some questionable handymen a few months back.  I just had the plumbing and septic finished so tested the hot water, only to find the element was already burned out.



I noticed however, that this 120v unit is wired via 10 gauge wire to a 30 amp double breaker.  This is questionable because I thought a 120v appliance would be wired to a single pole on the hot wire and run neutral to the neural panel area.



My question is, can I run the hot wire out of one side of the double breaker without safety issues, or should I definitely replace it with a single pole breaker?



I would normally not question the work, but everything these guys did already had to be adjusted, so I'm only naturally assuming this may need to be also.



If its safe, I would like to simply things and just connect the one hot and leave an open space in the other half of the double pole... Is this possible?



Thanks for your advice-
      

I have 200 amp service with a 50 amp service tap to the garage and another 50 amp tap to a small service panel for extra circuits. I have a 70 amp draw for a tankless water heater, 30 amp draw for the air conditioner, a 40 amp draw for the cooktop and a 40 amp draw for a double oven. I want to add another tankless water heater about 50 feet from the 200 amp panel. The new water heater requires three 50 amp breakers. How do I get the necessary service to the new water heater?
      

Hi All,



Planning on installing a Zip contract 2 point of use overhead water heater, 10 litre 2kw.



Query can I use current mcb & rcb installed in distribution box which was used for 3kw immersion water heater.



If not can I use a 45amp 30ma mcb and if so what rcb rating should I also use.



I am assumming that the old water immersion circuit would be ok or would the rating be too strong being it 3kw as opposed to the now 2kw.



Cheers,

Nutrifix.
      

I have a tankless hot water heater with the following requirements:

Voltage/Freq:240v/60

Wattage:21kw

Max amp load: 88

Min req circuit breaker: 2x60

Min wire size: 2x8 AWG copper (note:should be 2x6)



Amps to house is 200. Breaker box is 10 years old with space to add new breaker. The old 30 breaker will come out, new 2x60 in, and new wiring will need to be run approx 15 feet to location of old water heater.



Initial quotes from electricians via phone are all over the place and I have someone coming to house on Friday for a site estimate. In my understanding, the work is straight forward as stated above. What am I missing? Or what might the electricians be thinking I am not (besides pulling a $40 permit)?
      

Can i run 20amp double pole breaker for 120v outlets
      

I have a 15 amp breaker that services one light, one GFCI, one bathroom fan, one blade fan and one smoke detector. Can I also add one 750w baseboard heater using 14/2 wire?
      

Hello.

my electricity bills have been sky high for as long as i have been keeping track of them (less than 2 years).   i finally decided to try to track down the culprit.  I bought a watt meter to find phatom loads.  I found some and took care of them



However,

The electric hot water tank has got me thinking.  Could this be the cause of high utility bills?  The tank itself is ancient (RHEEM).  By the way it is rented from the utility company.  it is hard to tell the age because there is no date stamp, and the model number does not come up on the internet at all.  If i were to guess, maybe 25 years easily.  It functions in that I get hot water no problem



1.  Is it possible that the electric  HWT consumes way more energy than it should?, and how?

2.  Is there a way to track the usage?  My utility company installed a smart meter last year, and required an upgrade to get a new circiut breaker panel from old fuses

thanks
      

I was cleaning my garage and think I got some water into an outlet. This caused 2 gfi outlets to trip, a regular outlet to stop working, and one side of a double pole circuit breaker to trip. Now the gfi's can't be reset by pressing the button, and the breaker can't be turned back on either. Does the breaker need to be shut off in order to reset the outlets? It's been like this for 3 months now. Please help!
      

I have a 20 amp circuit running into my addition that I planned on running one baseboard heater from so I don't have a junction box. Now I'm putting one in the bedroom and one in the ensuite. I'm OK with using the thermostat on the heater instead of the wall so I'm wondering how to run the circuit from one baseboard heater to the next using one circuit and separate thermostats. They are back to back separated by a wall and I haven't closed in one side of the wall yet.
      

Hello again Gurus,



Will a double pole 15A 277v light switch work as a shut off for my air handler? I had to run all the electrical prior to them installing the central air and I wired a double pole switch from my 15A double pole breaker. I ran to the line/load ie black/white to the bottom posts on the switch. Thinking they can just run black/white from the air handler to the top. When the switch is UP> Live power to air handler. If it it's down (OFF), it means they can service the unit. Is my thinking correct on this? I couldn't find any other switches.



Thank You
