universal box fit?

Hi everyone! I want to know what is the minimum distance between two receptacles outlets in the same wall? Someone know what the electrical code said about that? And what it is the reason for that? I live in Toronto.Ontario.Canada Thanks you !!!!

Hi Folks, I've done some researching here and elsewhere concerning my topic, but I thought I'd run it by this group. I'm new to the site, but have been slowly increasing my DIY resume. Background: Our well pipe froze. We leave near the twin cities. We tried some last-ditch thawing efforts including hooking a welder to the pipes. Basically, one lead goes to the well head and the other to the pipe where it enters the house. Long story short, there must be some PVC somewhere in that pipe for a repair I'm not aware of. There is no conductivity, however when we first tried, the system grounded out somewhere. The wiring from our pumptrol switch to the well-pump controller fried as did the wiring from the pump controller all the way to the pump. Since the ground is frozen, we're running wire above ground for now. The wire is still 2-wire (actually 3: yellow, red, black). That matches what is in the pump control box. Since we thought we fried the pump, the well pump was pulled. It was tested and found functional. When the pump was lowered back into the well, they used 3-wire (actually four: red, yellow, black plus green ground). I've been heating the ground/pipes in the garage which is where I believe it froze. Our tuck-under garage puts the pipe only a foot or so below the freezing concrete as opposed to 8-12' below grade. I wanted to test the system, but the pump won't turn on. I have 240V at the switch and 115V at each of the two hots in the pump control box. I have wire caps connecting the above-ground jumper line right now, but they appear to be good. I can't hear the pump running in the well though. I've tried putting metal or a shovel on the well pipe to listen for resonation of the pump. Nothing. The only loose end, so to speak is the ground wire on the 3-wire coming out of the well. Can that just be loose, or do I actually need to ground it? Do I affix it to the well casing somehow? Your help is appreciated. --Ed
