I am wanting to purchase a 230v Single Phase 22amp air compressor, with the way my garage is wired i have a power cable coming from a 40amp circuit breaker going into an outlet in my garage that says its a 250v 50amp outlet that has a power wire going to another outlet that says its a 250v 20amp outlet. When i test em with my cheap analoge multimeter i see around 230-240v. Is it recomended to use those outlets with that air compressor? For safety reasons should i switch out the breaker to a 30amp or will the 40 be fine? am i going to need to replace the current socket with one that is rated at 230v and closer to 30 amps, would i be able to run it off the 20amp socket? thanks for any info. here is the compressor im wanting [url=http://www.lowes.com/pd_48365-1126-TQ3126_4294795216__?productId=3370338&Ntt=air+compressors]Shop Kobalt 5 HP 80-Gallon 155 PSI Electric Air Compressor at Lowes.com[/url]

Well, I >think< it is a buried electrical box. Project of the weekend is to make a few changes to the waterline in the front yard; easy stuff: a cutoff and a few extra hose spigots. When I dug up the line for the first spigot, I hit something not-dirt. Dig around a bit more, and find that it ... appears to be an electrical box. It is the same size as a single-gang box, and has what appear to be cables going into and out of it. It has a lid, and appears to be surrounded by, and filled with, some sort of black/white foamy material. The foam is kind of like styrofoam packing, but crumbles in my hand. As I tried to dig around, I thought I felt a gentle tingling at one point (not exactly like when you actually touch a live wire - similar, but much less intense), yet when I poke my volt sensing device (VSD) around the area, it doesn't come up positive (it is working, because I tested in a nearby socket before & after). I can try to post up a pic, if that will help. Let me know. Questions: 1) Does this sound like an electrical box? I mean, it looks like a duck, and I'm guessing it is a duck, but... maybe it's a goose? It's the foamy stuff and lack of obvious current that is throwing me off. 2) If it IS an electrical box, ... what do I do with it? I've disturbed/removed a lot of the foamy stuff which, I assume, is some sort of insulation and I may have moved the lid, exposing more of the foamy stuff inside. Do I trust that, because I'm not registering a current on my VSD, the box is still happily insulated & I can rebury it, or... is there an insulation I can buy? Or do I need to dig out the whole thing, replace it & rebury it? 3) Are there rules about how close to a buried electrical box a water line can be placed? When I first moved in, there was a spigot directly above this box. The whole area has been drenched for the past couple days to make my digging project easier. Yeesh. Nothing is ever easy at this house. Thanks very much in advance for any help you can offer! Shout if you want a picture of my mystery box.
