A normally open emergency stop switch seems like a bad idea to me. Safety switches should always be wired normally closed to fail open if the switch gets disconnected or damaged.
@@josephsager9425 I am very aware that this is painters tape and that it has next to zero holding power. I'm speaking from past experience where breakers were being kept forcefully open. At my first job one of them was nearly untouchably hot. [tbh idk how that place hasn't burned down yet]
Haven't worked on these but I do have first-hand experience as a gas station employee having had our pumps shut down with thr button. It electrically disconnects every pump, as well as every underground tank pump. If anything goes wrong turning it back on, it can take hours to fix.
@@Electchickn nope! One time was a bored kid who wasn't being watched. Other time was me, because a customer had yanked a hose off and was trying to reattach it, causing a leak. I'm sure if I worked in a bigger city you would've been right!
@KatieTheDev turning back on only requires the the estop button to be pulled out ,once this happens the contactors pull back in ,engaging so the power to the electrical panel that controls the tank field ,fuel pumps and possibly canopy lighting back on
For the normally closed estop situations, maybe used some insulated tap connectors and a short piece of wire to jump out the button while replacing it. Cut the jumper, remove the tap connectors and tape where the wires got pierced. Oh, the kitty litter is to help with gas or diesel spills.
The e stop functions by tripping the breaker? Knowing that its a NO switch, it seems like it just shorts the breaker when you press it? No fault to you for just changing out the switch, but that design is wild.

@@do4pc oh yeah! That’s actually an awesome idea. Guess it has to be already established to not interrupt power, but some electrician will thank you when they encounter it in 15 years lol
@@Electchickn 1st time just remove a few mm of insulation and use a short crocodile cable ;-) I´m working in electricity meter changing in germany, often under tension and sometimes we cannot cutoff the customer, even for the needed 4 minutes... a couple of 150cm 4mm² cables with crocodile clamps at both ends will do the job.

So you’re working in an active fuel station with live unenclosed contacts and ,during connect risk of sparks !! Sounds like this might be against regulations ,also stop buttons are normally used with break to fail as someone else pointed out in the comments .
Firstly, It should not be a "Normally Open" control as a SAFETY Switch.... For obvious reasons that if the circuit is "Cut" or "Disabled" or conductors incidentally damaged "As Open" this Shutdown E-STOP is Worthless 🤔 Secondly, You bypass(disable) "The Circuit" in the Fire Control or Equip Room before even touching that switch because I have come upon them where they were literally hanging out of the wall or damaged then triggered accidentally Grounding/Shorting upon disassembly. Third, make sure you completely understand that companies Fueling "Shut-Down" Procedures, Communications and Resetting per Guidelines. Sometimes upon E-Stop Activation alarms and strobes may disrupt facility in addition to Fuel Pump Disruption. Additionally a Central Station Monitoring may be involved with a possible Notifications to Local Fire Departments? Think of these E-Stops as if they were nuclear missile launching buttons, to you, thereby preventing an awkward situation. If you are fully prepared and have base contingencies planned..... THIS Risk? Can only happen with the unprepared technician, so preemptive communication IS Gold. 😊👍
This switch seems poorly designed, if you can bypass it without any safety system triggering it's not really a safety system. Interesting to see how this works, in curious if this is standard though.

@@shmuelglick4774 yes. This situation is was used as a shunt trip. Basically just shorting the circuit making the breaker trip
@@Electchicknstill sounds like a god awful idea
here in the UK it's a NC, litterally just a special double pole switch on the outside of the building between the breaker and pumps
A normally open switch on a SINGLE contact. The voltage is probably used as a trigger coil to trip the control power breaker.
@ yes
FYI, the kitty litter is a good spill absorber, e.g. a fuel spill.

Awesome video! Never seen anything like this before.
If you're taping your breakers open, I'm refusing to touch anything. I'm also letting FD know.
@ArkaniumGaming that's clearly painter's tape. It's not going to hold any breakers open, it's just covering them so employees don't touch them.

@@ArkaniumGaming Fortunately, modern breakers have an internal disconnector that will let them trip with a locked lever.
@@Nidkidful These breakers are from around the 80-90's [if not later]. They're running on heat, grease, and a false hope.
@@ArkaniumGaming some breakers are required to be locked on, like fire systems

@@mxslick50 too much effort for these guys haha. And yes the kitty litter thing clicked after I made the video
One fact of these pump cut-off switch: if there is a fire near an gas pump that means someone gotta go back and click it.

@@jag8926 shunt trip.
So far doing these switches, I have experienced three different wiring configurations. Hope you watch the next video!
The 120V goes to the aux.contacts on the contactor before the electrical panel that feeds the dispensers,the tank field ect.
'when your an electrician and not got one these' was expecting a camp bed and pillow to appear 🤣😳 or cleaning equipment 🤣😜 you been effected by the volcano?
@@peteb3365 thanks. No effected
You could always temp bridge the N/C wires on the switch side, install it then remove the bridge.

Whilst you're working on it, it should have been shutdown in my opinion, as there was an inability to trigger an emergency shutdown if needed.
warranty you fix today free fountain drink!
@@tyrstone3539 I have worked at these stations forever and they never offer free drunk :(
@ a shell like that owned by GPM or Majors never will
I have been to a gas station called robo and it’s in my area and there’s two button one for pump shutdown and one for container refill
First time viewer. FYI: Don't touch it. You'll break it.

@@lordbyrom100 nope. It was all shut off… but yes I agree it should be “fail safe” as they say. A normally closed system is better
I may be wrong, but does that emergency switch just short out the inside breaker and causes it to trip?
@@infinitepower6780 that’s essentially what a shunt-trip is. So yea
you could bridge the switch, and replace it
