Steps:
1. Heath breaks down electrical boxes into a few categories and explains their differences.
2. Heath starts by explaining that new work boxes are used whenever the walls are being opened up for work. This could be in new construction but also in renovations. They come with brackets on the side to nail directly into a stud from the side.
3. Old work boxes are used whenever the walls are closed up and small additions to the wiring are required.
a. Most of these have tabs that will pop out when pushed into the wall so that they can hold onto the drywall or plaster from the back.
b. They also make some old work boxes that come with angled brackets on the inside of the box that will allow you to screw through the box and into a stud without opening the wall.
4. Plastic boxes are most common and should be used with non-metallic cable wiring.
5. Metal boxes are used when the wiring is sheathed in a metal jacket.
6. Single-gang boxes are intended to hold one electrical device, like a switch or a receptacle.
7. Double-gang boxes are intended to hold two electrical devices.
8. Round electrical boxes are used for lighting fixtures on the wall, like a sconce.
9. Fan-rated electrical boxes are meant to hold ceiling lights with a substantial amount of weight. They do sell other types of boxes for ceiling lights, but Heath recommends always installing fan-rated, metal boxes so that any type of ceiling light can always be safely installed at that location.
Resources:
Heath described the best style of electrical box for various uses. In general, he recommends plastic boxes for switches and receptacles and metal boxes for light fixtures. Metal boxes are required when the existing wiring in the home is metal clad cable and must be bonded to the ground wire.
All of the boxes Heath demonstrated are available at home centers and electrical supply houses.

One additional thing that would have been helpful to mention is that the boxes come in different depths.
Interesting he doesn't ever use the semi sealed ones that can help with noise insulation.
Don' t waste money on cheap inferior blue boxes. Saw too many briken ones. Go to a real deal large electrical supply house and purchase fiberglass boxes. A little more money but bullet proof. Also fire resistant. If running wires in an unfinished basement or drop ceiling go with a 4 by 4 by 2 & 1/8" deep 1900 box. Don't waste money on shallow 1.5" deep boxes. First time that you need to install another wire in box you will be glad that you spent maybe 30 cents for a deeper box.
Could just call an electrician
LOL Now make this video about 2 hours longer and explain all the codes that apply to choose the CORRECT box
Imagine having room for only one switch or outlet
This meme made by Double Gang!
What about the new vapor tight boxes that are required in exterior walls in areas that have adopted the latest energy code? I suppose that could be a video in itself.
They are really only showing 1 and 2- gang boxes. When you start putting in 3-gang and larger, the plastic ones that attach to the stud tend to flex too much. I have had to remove numerous ones at my house when I replaced switches because they go too far into the wall cavity, and getting them flush against the drywall is a pain where they never look right. I replaced all of them with old work boxes with metal tabs. If I have to re-drywall, I use metal boxes with an adjustable metal brace behind them. The stuff that is allowed in residential construction is just painfully bad.
Question:
Where do you find studs like that?
All the big box stores' studs are half knots, bowed, twisted, and missing chunks where bark is.
The USA are so behind on the technology of Electrical installation. In Australia we can have up to 6 gang switch in the size of a one gang wall box.
Mud rings???
What happened to Scott for electric
What about junction boxes? What about the number of Romex that can be included in the box? What about the extra depth boxes and their use?
If your intrested in this as an electrician. Check out keizer or helia. German brands. Europe and the US are very different when it comes to this.
Way too many suggested video pop ups at the top of your videos …. very annoying!!!
Where is Roger?
did he retired
Junk plastic boxes…My 1990's era gray receptacle boxes are falling apart in the wall from just pulling cords out.
Thank you!
I was hoping this would include Junction box styles
I was worried about the blue plastic one day after I saw a wire burnout while in service so I took one out to the driveway, laid it on the ground and put the torch to it and it took a 20 seconds to catch fire. It immediately went out after I removed the flame. I slept much better that night.
didn't cover boxes sizes and how many conductors can be in each box size.
great job. more electrical videos please
2:05 What's the additional width for on the single gang box 2nd from the left?
Might want to add Low-Voltage boxes (Orange) for datacom. Some homes have LAN structured wiring, and "smurf" tubes run for future needs (fiber, Cat6/7).
I watched this to see you talk about the single gang lower right corner of the display. It has the 2 wings that slide in the sides with tabs you bend over inside the box. You never talked about this one which is commonly used.
None of them carry a Contractor's estate license !!!!!!
Never use those plastic ceiling boxes, use metal boxes in the ceilings for fans and fixtures.
He could mention that in Europe we use round boxes (outside diameter ~70 mm) for everything (well, in UK they use rectangular, but they are not part of EU anymore 😀 + I think Italy is also specific).
Watch out for those gang-bangs… boom.
Awesome presentation display
The plaster old work boxes should be standard for new and old work, they are absolutely lovely to use. Also way more solid then the drywall tabs style.
