    Is Romex allowed in an unfinished garage?

    Before tract homes around here got finished garages ( drywall, tape, texture, paint) most of the garages were open studs & any required or desired receptacles had the wiring dropped down into one stud bay then drywall was hung on that stud bay to cover/protect the wiring, it is cheap, cheezy and...

    The big difference in the electric terminology and installation regulations and practice in each country!

    There is still obsolete 2 phase power being used in some areas of the US, Philadelphia is one city where it still exists, I have never seen it though. Polyphase refers to either 2 or 3 phase, it would not refer to what you call "split phase" but is considered single phase...

    Need to upgrade main panel?

    Help on how to make the connection

    #2 AL is not suitable for 100A in your situation, only 90A, and 8/3 is 40A, as to flexible connections, the 50A CS locking devices used on spider boxes on construction sites would do well since flanged inlets, outlets, plugs, & connectors are available but not cheap...

    Ordered new breaker and want to make sure it matches the current breaker in the breaker box that needs replacing.

    HD is not the place to get information, other then where a certain item is, even that is hit & miss. I was at HD to get a tool & checked the Zinsco replacements & they were ETL classified not UL, but ETL is cheaper for listing and a NRTL, Nationally Recognized Testing Laboratory, as is CSA, & FM.

    How do I mount an outdoor electrical box to line in mast?

    Mounting anything on the mast runs afoul of most PoCo's rules, and is quite foolish just because of the fact there is no overcurrent protection at all on those conductors, as there are no fuses or circuit breakers on the secondary of a PoCo transformer. If I spent a little bit of time could come...

    Ordered new breaker and want to make sure it matches the current breaker in the breaker box that needs replacing.

    T&B made breakers that were UL classified to be used in competitive panels, the Eaton BR, C, breaker pictured is also UL classified to be used in competitive makes, the T&B breakers are no longer made. The UL listed/UL classified situation can be a pain, & Eaton makes classified breakers to fit...

    110V vs 230V

    110V & 220V are pre world war II voltages, 120/240V is the standard today, when some refers to something "110" or 220" as they are in almost every case a DIYer. What can get confusing is the rated voltages for motors and welding equipment of 115,200,230,265,& 460V, and the supply voltages of...
