  2. Surface-mounted NM / Romex into flush service panel

    Bottom line, what is your best advice for bringing "exposed" but properly protected) NM into a flush-mounted service panel? I'm looking to install a generator interlock on my service panel and am working out wiring the generator inlet to the new breaker. The 10/3 running from the generator...
  3. Portable Generator Hookup

    I am going to hire an electrician to help wire our house for a generator, but want to first get an understanding of my options. I learned about transfer switches vs interlocks, and interlocks just make the best sense for our needs. I discovered though that our main breaker is in the garage...

    So I recently purchased this Venmar unit on sales at Lowes (EVO5 500). I called the Venmar tech line prior to purchasing to see if the unit had a set of N.O. contacts so I could interlock it with my furnace. They told me yes, it has a set of N.O. and N.C. contacts. I got it all installed and...

  9. generator

    got me a 10,000/(8,000 run) some 5 months ago, it just dawned on me, I haven't done MUCH yet as far as prepping it for ready! I DID get it out, put wheels on, run it, fil tank, and stabil, etc, but that's it. I noticed I really don't have too many 110 outlets on there and can't see a bunch of...
  10. Neutral path between two main panels

  11. interlock paver for driveway

    Building & Construction
    I am researching interlock paver for my (double-car-width) driveway. Is the larger and thicker the paver the better in terms of stability, durability, etc? ie. 80 x 300 x 450 mm is better than 70 x 300 x 300 mm? Which one is better - 80 x 300 x 450 mm or 80 x 400 x 400 mm?
