I am not discussing amperage in this video.
When installing or repairing a 250v pool pump
switch make sure you install the correct type of
switch.
This video shows how some one used a stack switch
to control the pool motor.
The problem with the stack switch is that it only
shuts off one side of the power supply to the motor
leaving a hazardous situation at the pump motor.
The motor has windings, that if allowed,will carry
back voltage ,in this case,110 volts to the switch.
Both phases that make up the 220 volts required
need to be disconnected.
This video explains more about dpst toggle switches
and this • Electrical Wiring-Stac...
video explains more about stack switches.
Please rate and thumbs up the video if you like it

You are a Saint. I've probably watched over 15 different videos and none of them helped me understand like this one did. I now have the information I need to complete the job I was struggling with. Thank you so much! Subscribed.

It never ceases to amaze me what people come up with when wiring.

I can't believe some people, I work in the pool industry and run across your video (great explanation), this is really dangerous. Whoever did this deserves a shock in the balls.

Thank you so much, the way you use the mouse pointer to show exactly what was going on is VERY HELPFUL

Glad you like it. I get mixed feedback between making videos and doing a slide show. I try to mix them up a little!

Great info. I didn't think to check the switch to see if it was DPST. It was not. It is NOW! Thanks!

Phase isolation (as I would call it) is a requirement for our 415v equipment here in Australia too mate ;) Another easily avoided nasty situation!

I too value this video, but beware, there are other considerations that are likely not covered by this video. I assure you that there are many many more ways to screw up an electrical installation.

Lock out Tag out procedure requires verification of Zero State condition, that includes no electrical energy, before starting servicing. Some one could easily have been electrocuted at the swimming pool by just touching the metal box holding the switch, does it have to be metal?

I have read your question and I am not clear what your after. What is the circumstances that you are dealing with?Is this some sort of equipment that might have a main lug block that feeds all the motors?

What I am after is this, knowing that the NEC allows you to size your branch OCPD at 250% max for inversetime circuit breakers so in my case this would be 14 FLA X 2.5 = 35 (standard size) If I use this breaker what is protecting my conductors ampacity? Its only good for 20 A the breaker wont trip untill 35 A its only protecting for short circuits and ground faults Also the NEC say that a 14 AWG conducotr must be protected by a 15 A breaker, so in this case is i use a 35 A breaker should I use 8

Wow they would have been closer to code if they just run that extrnsion cord wire and pluged it in:>) BTW where's the GFCI for that pool pump?

@b2gills 11 жыл бұрын

You didn't mention that when the original switch is off, there is a combined 240V between the line and load sides of the switch. Which may be more than it was designed for.

Unless I size the breaker down and use 12 on a 20 A CB or a 10 on a 30 CB cuz thats what NEC says those conductors shall be protected by that CB raiting. obviously i can do that but lets say i didnt want to because i have lots of inrush current so i go with the max size 35 A CB do I use a number 8. Those are the questions what protects the 14 AWG wire with a 35 A breaker and should I use a number 8 for the 35 A CB this is all hypothetical.

This is related to 110v 2 phase to get 220v so dual pole switch should of been used, in places where 220-240v is the norm it only use single phase and a single pole switch would of been fine if that was the case (but it would of been IP rated due to it's location) , why this was done in this way is very poor and I am not a sparky and I understand how bad that is

does turning off one leg to a 220v pump cause any damage to the pump?

great video. Been going through my crawlspace and trying to clean up lots of "handyman" jobs myself. It's comical to see the rainbow of different types of cables with sketchy grounding and spaghetti that's not secured properly.

at first in the video you say you need a DPST and in the end you say DPDT but your diagrams were all that matters I think you just made a legitimate mistake

Hey friend your pretty condescending .. Obviously the person who wired it wasn’t electrician , they didn’t know better I bet they thought they were doing what is right ..I’m sure it was the homeowner that did the work. So if you would like people to do things like this right, keep putting information out for homeowners so they will have the info available because god knows you electricians $ $$$$ , cost an arm and a leg , and that’s why homeowners tackle more then they should. Don’t get me wrong you should make what your worth ,, so keep helping out thanks just less condescending towards people..
