I have a question regarding wiring a ejector pump in a septic tank. Would you consider it a classified location. Would you require a disconnect switch?

Just wondering up to my neck in _ _ _ _

Thanks
 
Yes, I would require a disconnect. Lockable too, in case someone has to enter the space.

Completly off topic.......but it might amuse - or offend some. Mods be kind.
One of my guys, though not a Cockney, used Cockney rhyming slang.
If I stepped out of my office and the phone rang......
"Your dog's barking" he'd say.
As in dog and bone rhyming with phone. Simple innit??:.............D

We had a project for Kimberly Clark. American personell were involved.
Septics he called them. Septic tanks - Yanks. Obvious..........

Didn't sit well with me. My dear wife is American from south of the Mason-Dixon line.
She was mortified to be called a Yank...........

Nor would I, they are not wired that way in my area. Residential, of course.

Non of the municipal lift stations are in my fair city either. This comes up for discuss from time to time; my opinion, Bevis and Butthead not withstanding, if you have enough natural gas concentrated in a sewer wet well to cause an explosion then you have a very unique situation.

Right, I think it's the same way here. Not my area of expertise but I see them wired with seal off fittings here, but probably they are just stuffed with duct seal instead of "chico". It would be hard to change the pumps out if you have to chip out a seal-off every time. :happyno:
 
Engineers and such determine classifications if any.
FWIW, I've never seen a SF or duplex pump where the area was classified. Sealing by duct seal etc. is still not a bad idea.

Large multifamily and municipal septics in this area are often classified.

With some very rare exceptions 430.120 will require and in-sight-from disconnect.
 
I was at the local city park one time and the Suez Environmental guy who does the daily rounds for all the pump stations was there, checking the one at the edge of the park. I walked over and looked down in the pit and heard the sewer water gushing in. I asked him if there is ever a lull in the action and he said that even at 3 AM, it's still gushing in. :?:blink:

+1 on that. Isn't that why we became electricians? So we can stay out of the doo doo

Yep. And to top it off there are stops and valves for water and gas everywhere, not the same for sewer.

I have to say that once on a call out to a lift station, the problem turned out to be a mercury float switch that was hung up and weighted down by having wrapped itself into a large mass of ... something I didn't want to analyze further. They asked me to free it up, I just cut the cord on it and installed a new one from the top of the well. They said "We can't leave that swirling around in there like that!" I said "The mass of stuff that tangled itself around the float switch was already there and not an electrical problem. I solved your electrical problem, I'm done."

Returning to the subject of the thread, all sewage wet well in the State of Washington are considered classified, for what that's worth. I think however that the point would be, there is no universally applicable statement you can make about it, the issue varies by jurisdiction.
