I do a lot of electrical work at a day camp here in my township. They have 4 swimming pools, a lake, food pavilion, buildings for extra curricular activities, rides, zip lines, etc. They are installing a new piece of equipment (I'll call it a ride) that requires a 20 amp, 240 volt circuit (unit draws 9.5A at 240V). I plan to install a 2-pole, 20A GFCI breaker and a run of about 80' of 3/4" PVC to the ride. Aside from the info I got from the side of the motor there are no manufacturer's instructions regarding how to connect power to the unit. I'm looking for suggestions as to what type of disconnect you would install at the side of the equipment itself. I was going to cord and plug attach this, but even though it may be an acceptable disconnect means it may not be wise to do this in the event of an emergency shutdown. So, would you install an outdoor safety switch, an emergency push-button or some other type of disconnect ? BTW, the ride is permanently installed on a flat-bed trailer but is, as such, portable. IMHO, they are not going to move it once installed. Thanks.
 
Good thinking about the safety off switch. I take it you're in an area that does not have county inspections.
What type of ride is it? You could do something like this. 1650457830233.png
 
EPO and disconnect for servicing are not necessarily the same thing.

EPO could even have multiple locations to stop whatever it is where a disconnect for servicing is typically one location and not only stops the unit from doing whatever it does, it also deenergizes the unit from the supply conductors where an EPO may possibly just stop a motor(s) or other work performing components from giving normal output.

A combination of both disconnecting for service and EPO might be a shunt trip breaker and multiple EPO buttons to operate it.
 
kwired has it- this is two separate issues.
As for a service disconnect, if the ride is moveable and might be stored elsewhere in the winter, then an L6-20 would do it, if really fixed in place then a bog-standard safety switch. (No 120v lights?)

As for an EPO.... if the manufacturer didn't see one as necessary, why add it unless the facility asks for it.
 
Good info. When you get it, the disco and connect will make more sense.
Remember with kids, its gotta be set up so they cant easily screw with the disco...
 
OK. Thanks for all the replies. I was at the camp today and got a chance to read the manual. Apparently this is a glorified set of 4 trampolines where kids are harnessed in and can jump to higher than normal heights. The unit came wired for 120 volts and is powered via a plug-in cord on the back of the trailer. That is just for the hydraulic portion of the unit. There is an emergency PB shutdown built into the control portion where the cord plugs in. It will also require a separate 120V GFCI receptacle to blow uo the air bags that the kids jump on. Kind of like a bouncy-house.

It's always nice to get a glimpse of the instruction manual so that you don't have to be like The Great Karnak and try to over-think what is required. :cool: Thank you all again.
 
Yes, they get inspected at the start of every season for all types of mechanical and electrical safety issues. That includes ALL the pool and pool pump bondings as well as any other electrical issues.
