    So as per my last threads, I have been put in charge of a project I am not qualified for and rather than wait for instructions to be handed down or a mistake to appear later after things have been drywalled, I am taking the initiative to figure things out when something sounds wrong. So I am...

    So I just did a job in a non sprinklered building. I had another more experienced foreman come help me and he said I need to change my connectors to rain tight since he just got called for it on his job.

    We are working in a smallish rack room trying to fit in a new cabinet. There are existing cabinets in the room, that have less than 1m working space. Was this rule added or changed from some smaller distance in the last 20-30 years when these older cabinets may have been installed?

    I'm asking because I recently told my coworker that the conductor length was supposed to be the "width plus depth" of whatever box you are working with. But he asked for the code rule, and I told him it was something my teacher at school told me and made us implement countless times. He was a...
