Everything seems to be working fine thus far. I decided to install a motion sensor light on the side of my house. I used a round fixture box to attach the light, I connected the light to a 1 foot piece of electrical wire (black to black, ground to ground, white to white) in the round fixture box (like you would a junction box) and mounted that box to the side of the house. The wire comes inside house into attic as you can see in the pic and runs into a junction box.


In order to provide power to this, I found a breaker that supplies power to one outlet (the ceiling outlet that connects to garage opener) and chose to use this circuit as my source. There was no junction box, it went straight from breaker to outlet. I cut the cable in the attic, ran the end coming from panel into a new gfci outlet. I ran a short cable from the GFCI outlet to the junction box I ran the light into earlier. The ceiling outlet then ran into that junction box. See photo below.

(Long story short.... it goes... breaker -> GFCI (because of light being outside) -> Junction Box (Which splits into the light and garage door opener)

Does this look acceptable?

 

I see a mixture #12 and #14 cable. #14 can only be used on a 15 amp breaker. The garage should have a 20 amp breaker. If it does the #14 must be replaced.

 

I had to double check, it does have a 20amp breaker. With that being said do I still need to replace it?

 

Yes, the wiring is too small for the breaker and is a fire hazard.

All of those connections could have been made in one box of sufficient capacity.

 

Disregard that. I guess I need to replace it with #12 then? (all of the white romex needs to be swapped).... everything else look fine? It has worked without tripping anything the last week and the GFCI tests OK. I just want to make sure it is OK and is acceptable for code.

 

What you have is unnecesararily complicated. See post #4.

 

Would you recommend me eliminate the second junction box and make all connections inside the GFCI box with the #14 replaced with #12?

 

Yes, all connections can be made in the GFCI box.That is the problem it might not trip till after the fire started.
