There is no spring on it?

Good luck

If it is 120VAC @ 15A, this will work

Yes exactly….i now think i should have a couple 115v circuits in this for lights. It wouldn't run for very long, just long enough to open and close the doors when needed in a power failure! I have this brand in my home in Northern Virginia 10-12 circuits. But yes, at the very least, i am leaning towards this solution from the start. Thx

120V 15A 4-Circuit Non-Automatic Transfer Switch

Secure your home with the 120V 15A 4-Circuit Non-Automatic Transfer Switch. Manual control, UL-certified, and ready for reliable backup during outages.

I do not like that "style" of transfer switch. You have to "guess" at which are the most important circuits. If you are wrong, it is a lot of re-wiring.

For home, or a very small shop (NOT 3 phase), use a generator interlock.

So...is there not a spring? The word "spring" is not in the other thread you linked, and is only mentioned here by mike93lx. For wanting solutions, you seem adverse to providing relevant information.

 

[BurtEggley]

Clamp an amp meter on it, see what the wattage is that it needs. Then you can decide the easiest way to power it next time in an outage. Worse, if the motor ever goes bad, what then? So, short term might be a power backup for it, long term might be to replace it with one that has a motor and manual override, like a chain drive.

 

[carcruse]

Do like I do with my furnace during power outages. At the switch, I disconnect it from the building power, add a pigtail with a plug and plug it into a portable generator.

 

[larry4406]

So the solution is to have a generator at the ready for the unplanned random outage and to assume the generator will always have fuel and will start on the 1-2 pull?

 

[gahrajmahal]

I have the transfer switch theoldwizard linked to connected to my gas furnace. It has helped us out multiple times. Attached find a sketch for my solution.

 

[My Old Tools]

Pretty simple to pull that one breaker, remove the wire and wire an plug on it to fit the generator.

Preparing for unplanned random power outages are one of the main reasons 3.4 billion portable generators were sold in 2024.

 

[The Cobbler]

none of the ideas on here, other than ones mentioning installing a manual over ride factor in a motor failure .
I'm confident would want a manual over ride .

I can't recall a commercial door that didn't have a manual/chain opener

I know I’m gonna get a 1 to 4 circuit transfer switch. I haven’t decided on exactly which one but I know this is what I’m gonna do. I’ve done this job before it’s not that hard. I just came to this forum to see if I could get any better ideas on the OP from people. I just have to power the door motor and a light. easy peasy.

The particular rare situation that the planets will align where there would be a power failure, and I would need to open this door to get some heavy equipment out is simply so remote. but I would like to have the capability to do this if I needed to I just need a way to get the power up there and I think the transfer switch will fill the ticket.

yes, very simple. There are so many videos on doing this. I pulled an electrical permit when I installed the one at my house. Here, way out in the park brush nobody’s gonna give a ****, but I’m pretty sure this will be good.

haha. rest assured, I think I have two or three portable generators plus the generator on the welding cart attached to the welder not a concern. it’s not for a freezer or a refrigerator. It’s to just pull open the door thx

do you think there’s a risk of back feeding?

 

[Cruzan80]

How would it back feed, if the circuit wires were removed from the breaker (and rigged into a plug) and plugged into the generator? There is no link between the generator and the panel in this case.

 

[Old tool guy]

. It is a BIG HEAVY door.

So? That calls for a PROPER GEAR RATIO chain fall. That door is not the first one like it to be installed, somebody already has a solution.

 

[Old tool guy]

Apparently it’s not rare, you originally posted here all in a dither because a worker had his truck stranded in the shop.

 

[BurtEggley]

did these doors have chains on them at one time?

Why don't you just put an interlock and generator inlet on the panel? Way easier than what you're suggesting if your panel will take an interlock and has available breaker space.



Most of us have never seen a commercial door that doesn't have a release and can't be disengaged. That's why you're getting all the "WTF". But seems like someone managed to get in a pickle...

 

[HalfTonTom]

I know the feeling. I was stuck on an escalator for two hours when the power went off at work.

 

[carcruse]

do you think there’s a risk of back feeding?

No, as there is no longer a connection to the building power source. I'm done it 3 or 4 times over the years. Only takes me about 2 minutes to connect the plug and the same time to reconnect it when power to building is restored. Portable generator sits outside with an extension run between it and the temporary plug.

 

[whateg01]

an APC would only last so long in frigid temps.

How many times do you plan on opening and closing the door while the power is out?

do you think there’s a risk of back feeding?

How?

 

[PCustoms]

OP needs to call an electrician, or a door service.

Too bad he has no idea who installed this...

 

[Old tool guy]

That’s terrible. Were you going up or down?

 

[nmk_61802]

That’s terrible. Were you going up or down?

Neither, it was STOPPED....

 

[nadogail]

I can think of ways to power a 125 Volt door opener, if the grid is down and you have a generator but no Transfer Switch.

McGuyver would open the Service Disconnect separating the shop from the Grid. Then Backfeed the disconnected shop circuit from the generator.

Extreme Situations call for Extreme Measures. Sometimes we just have to do something, even if it’s prohibited.

That had to be a *****! Standing still that long with both feet together would be brutal! Hopefully you were being paid by the hour!

I couldn't do it, I'd have to move around a bit to stretch my legs. Something like lunges or stair climbing would be perfect to avoid cramps

Hell no! It was dark and I didn't want to get lost. I'd only been working there for 18 years.

Yes. Mine is fueled ( with 25 gallons on standby) and starts on 2nd pull. Every time.

But aren't you now (or used to be) a linesman? Seems like that is actively betting against the home team...

I'm really hoping this is satire/sarcasm. (Or auto-correct got you)
However, your state (NY) does check out.

So one day there were some new yorkers riding in the bed of a pickup truck and it went off the bridge and into the river.
They all drown because the tailgate was stuck closed.

Bwahahahah.
No bets when its a sure thing.
Power will go out.
But yes and it ***** when you can't even get your own power back on . Mostly due to higher priority customers. Hospitals, 911 call center, police and fire stations.
Many times during extended outages I've had to drive past my neighborhood to go get other higher priority customers back on.

A very very long time ago before a lot of records were kept and switching circuits without calling it in were not that big of a deal...sure.
Pull up the facilities mapping (on paper then) figure out what switches to open to clear a fault and what to close (after making damn sure no one else was working on what you're going to energize). Bam.
Much more scrutinized nowadays.
