    Hello All I have a dedicated solar load panel that I sized and installed 6 years ago. It is a 200A panel and currently only has 2x 60A breakers to support 2-10kw inverters. I sized it in anticipation of installing up to 30kw and the conductors were sized for that as well. The solar panels and...

    I'm working on a house that has a sub panel (located in the same house) that is fed from a 6-3 NM cable that doesn't have an equipment ground. Was this allowable at any time? Do you bond the grounds from the branch circuits to the neutral at the sub-panel in this case (as long as there are no...

    I am trying to avoid taking out trees to upgrade the electrical on my house. I am considering bringing the power in to a sub panel first and then to the main panel in the garage. I want to keep some of the power at the sub panel for the condensing unit, pool, garden shed, etc. for 200 amp...

    I am installing a meter base on a house that has 2 breakers feeding sub panels. One is a 200 amp breaker feeding a sub panel for the main house. The other is a 125 amp breaker feeding a DADU (detached mother in law). The DADU is going to have solar panels. The solar guys want at least a 150 amp...

    I have an outbuilding that was formerly used in an industrial application, monitoring seismic equipment. It was completely functional and wired with it's own main shutoff switch, a 600v -->120/208 3 phase transformer and 200 Amp main panel (100 Amp 3 pole main breaker is already installed). When...

    Can anyone tell me if there is a NEC requirement for spacing electrical conduit,gas line and water in the same ditch? The PVC feeder conduit is for a sub panel to a DADU so this is not a service line. In Washington some utilities require the Service Entrance lines and gas lines to be at least...

    Just bought my house with a 750 sqft unfinished upstairs. Luckily 1 1/2" pvc was ran from the main panel to the upstairs for adding circuits. I plan on putting a 60A subpanel upstairs with 6/3 wire. Do I need to run THHN up the ~10ft lenghth of conduit and tie it to romex or can I just use the...

    when installing solar on a 125amp meter panel, we are allowed 120% of the max panel rating which is 150 amps, (ie, one 2pole 100 amp & one 2pole 50amp circuit breaker) that same rule applies to adding another subpanel, correct?

    I am retired so decided to pour a slab and install a little electric for my "RV" and I ran in to a few situations that I cannot seem to research and get an adequate answer too. So I thought maybe I should ask the "experts" here! A. ----If I decide to go the 6 "Offs" instead of a main breaker at...

    I have two questions 1) Is it against code for a 100 amp Main panel to feed a 100 amp sub panel? 2) Is it against code for a 100 amp sub panel to feed a 100 amp sub panel. In this case the first sub panel is being fed from a 200 amp main panel. My friend and I are having a difference of...
