How to Add a New Light, Switch, and Outlet Without Existing Wiring | Bedroom Renovation Part 3

This week we review how to wire a new light, switch, and outlet to an existing circuit. This project can seem intimidating, however it is easier than you might think! I go over all of the details and show you how to snake new wire through your walls with minimal drywall damage.

Thanks for giving me the courage to tackle this myself. Excellent work!

Great job with everything! Love the videos. Just some tips for next time, ultralight mesh tape is your best friend for drywall repair! Second, always make sure to put some metal stud covers anywhere a wire goes through so you don't have the possibility of drilling into your line in the future. It may bring the work up to code in your area and provide some safety. Have a great day!

For your first time doing this level of electrical work, you did a wonderful job using the existing receptacle to power new devices. There are three concerns I have with your work.

First, I see you leave too much sheathing on your NM cable. I see too many DIYers make this mistake. Doing so makes it way more difficult to fold the wiring back inside the box and violates NEC since it requires at least 6 inches of wire emerging from the sheathing.

Second, it's best to avoid mixing wire gauges. In this case, there's nothing wrong with using 12/2 since it's permitted for both 15 A and 20 A circuits. However, if this circuit is on a 15 A breaker, there's no need to spend extra on 12/2. It's certainly better than using 14/2 on a 20 A breaker, but mixing wire gauges isn't ideal and creates future confusion. Someone replacing a that failed breaker can easily swap the 15 A for a 20 A and possibly overheat the existing 14/2 wiring.

Last, always check the box fill. Many 1 gang boxes don't allow 3 sets of NM, especially 3 12/2, due to it's volume. If the box looks too shallow or you're unsure of it's volume, then it's best to replace it with a deeper box. It also makes running new cables way easier.

This one video has taught me how high end homes make there houses look the way they do with lighting

Couple things.. Why did you go with 12 gauge wires? Nothing wrong with it but that outlet is on a 15 amp circuit. Bit easier to work with 14 gauge. Also, you are not allowed to run wires through a plenum air space (the hvac return) unless it is run perpendicular straight through it. Love the remodel though!

I have a question. When you wired the outlet and light switch on the left side of the bed, I'm curious how you did that. Can you explain that deeper?

[KINGDUCEY]

what program did you use to come up with the 3D design for the bedrrom?

[lwolf]

I would've ran the wires behind the baseboard to avoid having to tape, mud, sand and paint that cutout you did. always remember to work smarter not harder, you have to use measuring tape so both have correct height....but other than that good job 👍🏽

Did you add any support to the light box in the ceiling ? those tiny wings that come on the box really ain’t enough

[doseofreality]

Oh my god, why didn't you just pig tail everything to the outlet.

I hope you’re not hanging a fan from that old work box lol

Everyone before thanking you for a good job gotta put their two cents in.smh.Why the hell they watch your videos if they already know how to do it?This is for ppl that don’t know how, like myself.I actually liked your video and appreciate the help.The other ppl putting their two cents in can eat fecal material.

You’re definitely not an electrician and doesn’t look like your grounds were spliced properly. But yea thanks for not really teaching anyone the right way
