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. The new heater is in place and filled with water.JA: Anything else we should know to help you best?Customer: No, I'm just curious why the wires out of the box aren't red and black rather than white and black.

Similar to one I saw here: I have a 1.25 HP pump (115V pulls

Similar to one I saw here: I have a 1.25 HP pump (115V pulls 17amps) I use to water the lawn. It draws from a spring and needs to be turned off by a float switch. But I only want it to come on twice a day (adjustable timing for seasons). Also the pump currently overheats the plugs when it runs - so I need to rewire the wall switch/outlet where it plugs in. I tried a timer from lights but there must be a better timer (with ground?). I don't know how to wire this up.JA: How long has this been going on? And how severe is the problem?Customer: Currently I use a wall switch to turn the pump on and off manually. It worked, but obviously making it automated would be better.JA: Do you plan on doing the work yourself?Customer: Yes.JA: Anything else we should know to help you best?Customer: I messed up last summer by wiring a plug on the end of the float switch, and plugging the pump into it.... didn't work - now I have read the float switch only has one wire!

I'm reading some blueprints and there is one symbol on there

I'm reading some blueprints and there is one symbol on there I am unfamiliar with. There is no chart describing it either in symbols.It's a couple short lines going across the middle of a wire run between devices. It has a dot on one end too. Kind of like a Power Pole would have a couple T's across the top of slightly different lengths.Sound familiar? I have the blueprints if you want to see a screen shot of what I'm talking about. Tell he what it is, if you can. I think it's just there to piss me off because I thought I knew it all by now but still run into things I have never seen before even after 4 decades of this game.Tanks!Sparky

I'm adding a sub panel to a shed. 40 amps 120 volt. Is there

I'm adding a sub panel to a shed. 40 amps 120 volt. Is there any reason I can't take my 40 amp wire and wire nut to splice to the two bus bars so each gets 120? I don't need 240 and it seams safe to do this.

Thank you! My bathroom exhaust fan/light has a continuous

Thank you! My bathroom exhaust fan/light has a continuous "alarm" sound... similar to an home security alarm system. We have removed the exterior light. It seems internal. I'd appreciate any advice... thank you!JA: I'll do all I can to help. How long have you been dealing with this?Customer: About an hour. It has gotten louder. Constant except sometimes stops for s second and resumesJA: Do you plan on doing the work yourself?Customer: Not if it's electrical. Trying to figure out what is causing itJA: How old is the system in question? And have you consulted an electrician yet?Customer: We've left phone messages but have not been able to reach one (after hours). The house is 12 years old and has an alarm system. We went to the garage to turn off the circuit to the bathroom, and can also hear the sound in the garage (opposite end of house from bathroom)JA: Anything else we should know to help you best?Customer: It seems like an alarm is going off... like it's built into the ceiling. Very odd since we hear it on opposite ends of house. I hear it loudest when near various ceiling lights

What is the standard circuit breaker for an wall oven and

Greetings,What is the standard circuit breaker for an wall oven and for a dual fuel range? Aren't they typically 40A? The installation instruction I am looking at for a Kenmore Elite wall oven (3.4kW) calls for 20A while the stove (4kW) is also 20A... Thanks for all your help.Peter

Over the last few months at random times my roommate and I

Over the last few months at random times my roommate and I would smell something burning almost like a hot copper smell but it would go away. This usually seemed to be around when the AC would kick on. My roommate always said he smelt the copper smell while i was away VERY strong coming from the closet housing the air handler for the AC. Finally a few weeks ago I was playing with a sub woofer in my room and it blew like it had been hit with a surge. The plug the sub was attached to immediately started making the sounds of an overloaded socket and the wall above the socket started to vibrate. I also noticed a ground hum coming from my master bathroom light fixture. All the other sockets seemed to be making the noise to a lesser degree. The AC unit also smelt very strong of copper when the cooling was on, with just the fan.. no issue. I unplugged everything from the house and after while cut the breaker off. This got everything more under control. AC guy came out and said nothing was wrong with the AC but was certain that he thought there might be dirty power. I went and got a socket tester and found a bunch of my sockets were reading open neutral. Is there anything I can do myself to help fix things? I know to stay away from the main breaker. I just dont know when the landlord will send out an electrician
