    I have a fairly large room, a loft in a barn that will serve as a classroom, that I am installing electrical baseboard heaters in. I am installing four 2000 watt baseboard heaters: two will be off of one 240V 30A circuit; and two off the other similar circuit. I would like to install a...

    Hi, I have a 7.5KVA single phase pure sine wave inverter, which stores power in ten 12V 200Ah batteries. What is the best/most efficient battery configuration (series, parallel, series-parallel) for connecting up the batteries for max output, capacity and minimal energy loss?

    Thanks in advance. I'm just trying to wire a table lamp with multiple bulbs and I have a few questions. I've wired chandeliers several times but I always clustered the wires - this won't work on this lamp. I've attached a diagram. I believe I've drawn a parallel circuit but not sure. Couple...

    Do I need two dedicated circuits for a bathroom? I am running a 12amp breaker with 12/2 wire for the GFI receptacle in the bathroom. Do I need a separate 15 amp circuit with 14/2 wire for the fan/light and vanity light or can I piggy-back off of the receptacle. I am in Montville, NJ. Thanks...

    Ok, so I'm not onto tackling the electrical in my DIY home addition, after recently finishing the rough plumbing work. My county in MD follows the NEC 2014. Attached is the layout of all the fixtures for this 1-room (office), 2-bath addition. The only thing I have left out is the individual...

    Hello, I just discovered some wiring in my house that is crossing between two circuits. I'd like some suggestions on how to proceed. It's basically an outdoor light controlled by two switches, with power coming from one circuit and neutral going to another. The wiring gets spliced together...

    Hi, I'm new here and have been struggling with this problem at my new house. The living room ceiling fan/light with a remote has not worked since we moved in a couple months ago. The fan and receiver are good, because I switched it from my bedroom where it worked no problem. In the junction...

    Yesterday, I plugged my small vacuum cleaner into the same outlet as my small a/c. The circuit went dead. I went to the fuse panel and replaced the dead fuse (tested with a multimeter). The circuit is still dead. Not only that, I later discovered that everything on that side of the house is...

    I recently bought a home in Brooklyn, NY, and in the process of changing out a receptacle, I noticed that I had two 20 amp circuits sharing the same neutral. It's my understanding that this is fine as long as the 2 circuits are on different phases. What I don't know is whether my circuits are...

    Trying to hang a chandelier in my daughter's room but having problems. My husband tried hanging a different one in her room last week but something went wrong and sparks were flying in the room and the circuits were tripped. I turned them back on and got a new chandelier. Today, I attempted it...

    i was wondering if i can share a 20A circuit between the garbage disposal and a bathroom power outlet. i know that it is recommended that a garbage disposal be on its own dedicated circuit. thanks

    So here is what I want to do. I would like to create a three-sensor circuit that would let me know the winner of a pinewood derby race. Essentially it would be three pressure plates that the cars would hit at the bottom of the track, but I would like to figure out a way to show racing results...

    I'm remodeling my kitchen and am splitting off receptacles and adding new 20A circuits. I'm also breaking off the feed for the bathroom from the kitchen light circuit. I have all the new feeds pulled into the boxes and everything hooked up. I'm trying to decide what to do with the old...
