Installing new electric water heater. Wires coming from our

Installing new electric water heater. Wires coming from our electrical box are ground, white, and black. The wires for the old water heater were red, white and ground. The grounds were connected to the ground screw and the white from the box was connected to the black of the water heater and the black from the box was connected to the red from the water heater. Now for the new water heater. It comes with a diagram that shows a red and black and ground coming from the box. It also has a little black smart grid box with a ground, a red, and a black. The diagram with the water heater shows all blacks connected together, all reds connected together, and grounds connected together. So, how do I connect this? The circuit breakers are off and I have checked the wiring with wire circuit tester. ThanksJA: How old is the system in question? And have you consulted an electrician yet?Customer: The house wiring is brand new, about 8 months old. We had the house rewired. New box, new wiring.JA: Do you plan on doing the work yourself?Customer: Yes, I have hooked up water heaters before.

I lost power to a portion of my home during a storm. I did

I lost power to a portion of my home during a storm. I did some "research" that told me to turn off breakers in the box, the flip the main breaker on and off two times. I did so and power seemed to be restored. The clock is working on my stove but it won't heat. Some of my outlets are fine but where my microwave was plugged in, I turned on the microwave, the light inside came on, then faded and the table wouldn't turn. I have a window unit in my bedroom on its own breaker. Now, it will run but not cool, for a couple of minutes, shut off and my TV went off, too, then they come back on. My water heater isn't working so I was going to turn it off but when I flipped the breaker, the TV also went off. My electric company is a co-op and no human to talk to on weekends. Is there any chance the problem is on their end? I am pretty handy if I know what needs to be done. I can not afford to call in a professional. Thank you.

I would like to convert a currently unused 240v 30a circuit

Hi, I would like to convert a currently unused 240v 30a circuit to a 120v 20a circuit. The circuit was used for an electric water heater that is no longer in use. It is 10/2 with ground and I would like to junction a 12/2 with ground to a 120v gfci receptacle for my new tank-less gas water heater. Can I use one of the 240v hot wires as a neutral for the new circuit as long as I replace the 30a breaker with a 20a breaker?JA: How old is the system in question? And have you consulted an electrician yet?Customer: Wiring - early 80's, new water heater just installed. I have not consulted an electrician as of yet...JA: Do you plan on doing the work yourself?Customer: I doJA: Anything else we should know to help you best?Customer: I will be replacing the double pole 30a breaker with a single pole 20a and blocking the space leftover due to the difference of the two

I live in a two family home, I rent the downstairs. It

I live in a two family home, I rent the downstairs. It appears the water heater and common areas are tied to my meter. How do I find out without question everything tied to the electric meter I'm paying for? The electricians I've called have been stumped as to why the owner can't tell me. But he knows and won't I need this info to force them to fix this by installing a 3rd meter for common areas

Dear Pearl, I am in the Dominican Republic. I have two 110

Dear Pearl,JA: I'll do all I can to help. How long have you been dealing with this?Customer: I am in the Dominican Republic. I have two 110 lines. I would like to protect the 220 V pump of the swimming pool. Do I need two CHSPT2Max surge protectors? One for each hot line?JA: Do you plan on doing the work yourself?Customer: Sure, I am in a small village and there are no qualified electricians here. I am Dutch.JA: Anything else we should know to help you best?Customer: Yes, the situation is a bit complicated.We have 14 hours current from the street line. Mostly during the night. In the night an inverser is changing the batteries and during the day the inverser provides electricity in the house. The pump of the swimming pool is heavy for the inverser and only works during the time there is electricity from the 'street'. The quality of the electricity is low and there are a lot of fluctuations. I have a new 2 pole circuit breaker. Is this for only one hot line?JA: How old is the system in question? And have you consulted an electrician yet?Customer: Part of the system is 15 years old, other part have been added last 3 years. It is difficult to find a qualified electrician. I tried several, but ithe system is a mess compared to a system in Holland.
