Hi everyone, Merry Christmas and Happy New Year. I'm new to this forum and joined because I have lots of questions about electricity that only professional electricians can answer. I'm far from it and I don't know any electrical terminology as well. Would really appreciate if you can answer in simple English. I'm living in Canada British Columbia who has OCD and obsesses about electrical answers I cannot find the answer to. I am NOT suicidal or intending to hurt anyone. I asked my electrician friend but he recommended I put it through a forum where more experts can help me. Would really appreciate your help so that I can relieve my anxiety. So the diagram is attached. I'm trying to understand the electrical relationships between each hole. This is a 'normal' standard wall circuit not in the kitchen, like in the bedroom or something and not hooked up to any light switch. 120 volts as per normal. Imagine a person is standing on carpet or laminate floor in an apartment. 1) Would the person get more of a shock touching A1 and B1 if they were in a house, standing on carpet/laminate, compared to in an apartment 30 storeys off the ground? Why or why not. 2) Please confirm if the following is correct. 1) IF a person touches A1 and B1 with one hand, they will get shocked. True/False 2) If a person touches A1 and C1 with one hand, no shock. True/False 3) If person touched B1 and C1 with one hand, will get shock. True/False 4) if a person touches A1 and A2 with one hand, no shock. T rue/False. Why? 5) If a person touches A1 and B2, will get a shock, at the same voltage/power/impact as touching A1 and B1. Is this true and why? This is assuming there is no change in the person's sweat level, or change in surroundings etc. 6) if a person touches A1 and C2, no shock. for same reason as there is no shock when touching A1 and C1. 7) If person touches B1 and A2, there will be a shock. At the same voltage/power/impact as touching A1 and B1, or A1 and B2. This is assuming there is no change in the person's sweat level, or change in surroundings etc. is this true? 8) If person touches B1 and B2 with one hand, they will get shocked. Same vltage/power/impact as A1 and B2? why or why not? 9) If person touches B1 and C2, will they get a shock? 10) if a person touches C1 and C2, no shock? I assume if you touch 3 or more of the components above instead of 2, for example, A2, B2 and C2 all with one hand - the shock will be greater than touching just A2 and B2? Is there some kind of machine/tester that one can buy/use to test this (including the severity of the impact/voltage/power of the shock) so that one can find out? Thank you so, so much. I really, really really appreciate this. merry Christmas and happy new year.

Hi all, I'm a teacher at a small high school and we are planning on starting a culinary program here in the next couple of years. The "when" is dependent on grant funding we haven't received yet, so everything is pretty theoretical right now. I'm trying to iron out as many details as I can in advance, and one thing that's come up is that we will have to install an industrial freezer in order to meet food safety requirements. It's the understanding of some of my colleagues that industrial freezers use a higher voltage than ordinary freezers. I don't know much about electrical issues. Here are my questions: 1) Is it true for all industrial freezers that they require a higher voltage? 2) How hard would it be to install an outlet for such a freezer (220v I think)? 3) Would it be best to have a professional do it, and if so, how much would that sort of thing cost? The kitchen would most likely be installed in a portable building where we already have a small kitchen area (two sinks, a fridge, some hot plates). The school has two portables and one permanent building, so if for some reason installing in the portable wouldn't work, we could look at doing it in the permanent building, though space would be an issue. Thanks for any advice.
