Bob Schmidt shows you how to use an electrical box extension with standard plastic electrical boxes, during remodeling. When adding drywall, tile, wood over existing surfaces.
Video Rating: 4 / 5


  1. This is a perfect example of why I cannot recommend the typical homeowner or Diy’er doing any re-wiring of box without consulting a professional. Although I would not hesitate myself extending copper to copper,even thou I am not an electrician,not all people have seen as much as I have to have enough confidence to do the job properly.The fact that you have misgivings about the connection should tell you to consult a qualified electrician.Every person needs to know that he has limitations.===Bob

  2. I generally do not recommend any re-wiring of electrical boxes by non-proffesionals even something that seems simple could become complicated quickly===Bob

  3. to make a long story short I came in a sort of a non religious mission, but now is almost over and I am free to return home. I find your channel grate because I will bild a home in argentina, thanks again!

  4. I understand that you are using the non metallic boxes due to your locality is it possible maybe on some of your videos where you can show wiring using metallic boxes ?

  5. Code calls for space according the number of wires in a box. It is OK to add a pigtail as long as the pigtail and wirenut are inside the box. Wirenuts/splices outside of a box are not OK according to the NEC. Also a splice can be made if a wire run is to short by adding a box somewhere along the wall, basment or attic. The splice box has to have a blank cover and be assesible. You can not bury any box anywhere. Always consult the UBC, NEC or your local building codes.

  6. This is all well and good, Bob, but try to find one of those blue plastic boxes at any DIY store and you’re out of luck. Home Depot doesn’t carry them. Menards? No. Ace? No. Lowe’s? No. What’s the secret handshake?

  7. Thats odd because I purchased mine at my local Home Depot,I suppose all stores do not carry all same stock items but I would imagine all electrical supply houses would.You can also look online to find providers in your area+++Bob

  8. I found them at my lock Lowes and Home Depot. Do you like on the moon or something?

  9. how do you know if the extension will be the right size? are there different sizes for different thicknesses of drywall?

  10. First, it depends on your local codes. In the midwest USA, many states require you to use only metal. You can use a ground wire if you’d like on some installs, or use the conduit as the ground. Again, too many codes to list here. WI you can use Romex and plastic boxes, IL you cannot. depends on where you live.
    Second, If you don’t recommend a DIYer to do what you show int he video – then don’t show your video, it makes no sense. Us professionals don’t look at the videos to do the job.FWIW

  11. FWIW Each person has their own comfort and knowledge level about basic repairs and minor remodeling. If you called a pro every time some part of your home project fell out of your area of expertize your project would get quite expensive(even if you could get a pro to show up and bid a small project). I showed a situation where this applies, not all situations,and I believe the people looking for assistance with this particular situation will find this useful+++Bob

  12. Nice video I would recommend pig tailing rather than relying on receptacle device for continuation of hot and neutral conductors.

  13. Video is okay for apprentices trainees to check out regardless of local codes it’s always nice to know all alternatives it helps one to become innovative. Remember metal is a great conductor of electricity, also depending where you live in example coastal region metal disinigrates or badly oxidizes, or ranches got rodents that’ll work their way past plastic and romex sheathing CA is one state where applying codes to enviroments can be complex how bout ranch on beachfront love those…

  14. Great job for your scenario. Pigtailing current carrying conductors would be nice

  15. I believe code doesn’t allow both of the terminals to have more than one conductor fastened. I ALWAYS pigtail.

  16. Very informative and useful information for me. I’m planning on doing a tiled backsplash in our kitchen, and this is just the sort of information and advice I needed. I was worried about how to allow for the new tile thickness for the electrical boxes…and voila…this is the ticket. Looks easy enough, and will save me some bucks on an electrician. Now my wife can spend those dollars on nicer tile for the project instead of hiring someone to re-do the electric boxes. Thank you sir!

  17. @jcaimhigher If you don’t watch the videos, what are you doing here?!?!?
    ps Proper grammar is WE professionals.

  18. you’re the man bob! this was the first video i found when searching for box extenders and this is perfect! thank you so much.

  19. @HomeRemodelWorkshop Same here. Couldn’t find at the big box stores or ACE. ?? Will try the elec supply places next, even if they are not as close. ALSO, re: checking the power is off: “How Many Times Must A Man” get knocked down?, before he remembers there are constant on lines running thru a switch that is “off”? Just learned this AGAIN at my sis-in-laws 50 y/o cracker house here in Central Fla. And I was on a step ladder installing a ceiling fan!
