The site navigation utilizes arrow, enter, escape, and space bar key commands. Left and right arrows move across top level links and expand / close menus in sub levels. Up and Down arrows will open main level menus and toggle through sub tier links. Enter and space open menus and escape closes them as well. Tab will move on to the next part of the site rather than go through menu items.

Good morning, I read your questions every morning and appreciate the guidance. Hope you can help me once again here. I connected the output circuit of a PV system to the bus of a feeder panel in a building using a 60A 2-pole breaker type OCPD. The PV output circuit has a max current rating of 44-amperes. At 125% the 44A output circuit is 55A so we used a 60A breaker. The inspector still failed the inspection and is telling me the 60A breaker used for the PV output circuit must be installed at the opposite end of bus from the OCPD protecting the bus. The bus is rated at 225A and protected by a 200A OCPD. I cannot find this rule in the NEC®. Regards, Roger A.

Hello, I recently wired a new construction house, and the owners framed in and made plumbing accommodations for a future bathroom. There is nothing installed in this space yet, no toilet, bathtub, sink etc. I did extend the 20A bathroom receptacle circuit from the completed bathroom upstairs, down to a wall mounted box and receptacle in this future bathroom space. Is this a code violation? Thanks Ralph M.



Good morning, Ralph. The term “Bathroom” is defined in Article 100 as:

An area including a sink (basin) with one or more of the following: a toilet, a urinal, a tub, a shower, a bidet, or similar plumbing fixture. 

The space described in your question does not technically meet the definition of a bathroom, so the installation described would not be permitted as it does not comply with the requirements in Section 210.11(C)(3).
