Hi Everyone - I have a 80amp sub panel in my basement – it’s connected to my primary panel via 4AWG and it’s about an 80’ run. I want to run electric out to two sheds which are approximately 110’ from the sub panel. The electric will mainly be used for lights and receptacles. I do not plan...

We're constructing a new house on a new lot without any electric in place. The utility company has its line at the start of our property and we're placing our meter down there (320Amp panel) and bringing up 320Amps to the main panel in the house where it will branch off 100Amps to the garage...

I am new to this so bear with me. For starters I am in my garage, which is separated from the house. My garage is powered from the house box with a 240 breaker that runs out to a small breaker box in the garage. In the garage when nothing is on one circuit of outlets have about 121 volts and...

I have a farm and need to put in a mobile home for employee housing. I need to get power to it and am wondering the best approach. I have power running in 4 directions from a main power pole. The trailer site is located 4 to 5 hundred feet on the other side of a building that doesn't use much...

When a large appliance starts, should I expect the lights to dim? I think lights dimming means that the voltage is dropping. Is this really hard on appliances? Or is it hard only in theory? In some ways I tend to think nothing bad will happen if I don't fix the problem. I think I have too...

I have a need to distribute 120v lighting and receptacle circuits as far as 500' from the nearest structure. I started a thread that has expanded in scope and I wanted to start a separate one only for the idea of using an external transformer. I like the idea of running 240v out 300' or so...

I'm planning to trench about 350' to run a 120v branch circuit from my house to my property line at the county road. I want to add approximately 15 amps of lighting along my property edge. I was investigating the wire size needed so I could order my conduit. I read that NEC requires 3% voltage...

I have installed a AVR to a building 3 phase AC utility feed. The AVR is installed at ground floor and the meter is in second floor. AVR is set to 230V output. Here is the reading from the meter. Phase A --------- Vrms = 225.5 V Arms = 0.992 A PF = -0.06 P = -13.4 W Q = -189 VAR S = 223.8 VA...

Hello, I am sizing wire for my service entrance and want to make sure that I purchase the right one. I am trenching 150' from my meter pole (approx. 35' from an overhead transformer) to serve a 200A panel at the house. The calculated load for the house is ~90A. I wanted to allow room for...

I have two phase power wires connecting to breaker panel and it is 200Amp. I am measuring the voltage of both hot wires those going to the panel. Normally each one comes 123Volt and around. During this time, my all appliances works correctly and no fluctuate in lights. But sometimes one hot...

Hello all, I moved into a house in the USA (WA) later last year. I lived in an apartment before (think it was a 90s build). In the apartment whenever we plugged and turned on the vacuum in the lights would go a little bit dimmer and remain dimmer until it was turned off. When I moved into our...

I recently spoke with a builder regarding plans for a new home on my rural property. We're looking at something around 1800 sq ft. The builder indicated that they install 200 amp load centers on anything that size (as I expected). I told him that based on my current plan, the electric meter...

voltage drop Hallo Experts I intend to operate a 0.5 Kw 240V single phase water pump on a river. The pump will be 700 m from the nearest single phase 240V power supply. Using 2.5 mm2 + earth power cable, the voltage drop over 700m would be too large to operate the pump. Is it possible...
