am installing multiple lamp holders for my garden bed to use par 38 flood light bulbs. I purchased all weatherproof materials that is rated for outdoors ( dug trench, purchased uf 12/3)
The power source is coming from the garage right to the lights, then after the last light will be the switch inside the bar. What would be the correct way to connect all of these lights to the one switch? Also want to put an outlet and another light inside bar. I’ve attached a diagram for better understanding
Since you are using three wire everywhere.....
the black will be always live and just carried thru every light.
Each light will connect to the white neutral wire.
Each light will connect to the red wire which will be the switched hot.
At the switch end.... the switch goes from black to red.
Since you have always live power at the switch you can connect your receptacles to the black and white wires.
All ground wires are interconnected.
You will have a red and white splice to connect the light to in every box. If the light socket wires are too short to reach the splices then you'll need pigtails from the sockets.
You can put in as many switches as you want and in any location BUT if any switch is on the lights will be on.
If you want two switches to completely control the lights from either location then you'd need a three way circuit. Your wiring does not allow for three way wiring.
Hello everyone,
So, I recently bought a used tanning bed. The people I bought it off of say it works great and have never had a problem with it.
They said it was hooked up to a 120v 20A circuit.
I hooked it up to a 120V 20A circuit but it just hummed and no lights came on.
This is where things get complicated. When we were moving the tanning bed the black box was very heavy so we disconnected it. My friend disconnected it and then never reconnected it. When I went to set it up I called him and he told me how he disconnected it. After I turned it on it just hummed. I thought it was the box. I called another electrician friend and he said the box was wired wrong. He said the H’s and X’s should never be connected. After I rewired it then plugged it in it tripped the breaker without even turning on the bed.
I asked the people I bought the bed off of to check there panel for a dual breaker other than the 40 for the stove and the 30 for the dryer. Sure enough there was a 240 dual 20A labeled TANNING BED. 🤦🏻♂️
So I wired the black box up the way it was before…or at least I am 90% sure I did.
I bought a 240v 20A breaker and changed the wires.
Still a little Leary I disconnected the black box from the bed and tested the voltage.
The voltage coming from the plug is 235v. The voltage coming from the transformer or black box is 270v. The bed is rated for 230v 20A and 60hz.
I don’t understand the purpose of this black box and why it is increasing the voltage so much.
I thought maybe it was for isolation purposes since the bed is all metal but the voltage seems excessive.
I want to plug the bed into the black box as this is the way it was working before but my gut is saying maybe not the best idea.
Any input regarding this?
Thanks ahead of time for any replies.
Hi guys,
Recently my lights have started flickering a lot, mainly in my basement when the ac is running. I installed the recessed lights in the basement and I feel like they've been fine for a while but all of a sudden they started flickering more and more. Any suggestions on what to look for? I read that an ac capacitor could be the culprit. Any help would be great!
Below is a video, not sure if you can view it or not.
