Ground Up or Ground Down

The age old argument of which is correct, ground up or ground down. A lot of electricians in the field get confused when deciding whether or not standard grounding receptacle should be ground up or ground down. The origins of this entire argument actually stems from a corporate officer in a McDonalds' corporation, according to sources there was a employee that did in fact accidentally drop a metallic tray down the back of the table which slid into a half seeded cord cap. A large flash occurred and the employee suffered some burns. The incident created a policy within the McDonalds corporation mandating that receptacles from that point on should be installed with the grounding terminal on the top, and receptacles to be mounted on a horizontal position with the grounded side, i.e. load side facing up. When facing the receptacle, the grounding terminal will always be to your left and the grounded terminal will be on top. The issue was brought to Pass & Seymour major manufacturer of receptacles and other devices. The debate however, began to rage back and forth between the two factions that we call the smile face group and the ground-up group. The issue was so large and important that at one point a proposal was submitted to NEC but it was ultimately rejected. It has never been adopted again, as such there is no actual code requirement, it is strictly just a preference. The only time it would be an issue that would cause you to fail an inspection would be if there is a city ordinance that is above and beyond the NEC requirement. Mitchell Tolbert

  1. Hey! I will be looking forward to visit your page again and for your other posts as well. Thank you for sharing your thoughts about electrician in your area. I am glad to stop by your site and know more about electrician. Keep it up! This is a good read.
    Most jurisdictions require qualifications to do work on any electrical apparatus with voltages above a specified electric potential to ground. This is normally anywhere from 24 to 100 volts depending on the governing body. Many companies have their own voltage limit rules as well.

  5. Since everyone is asking questions about electricians. Then maybe I can get my question answered here. So me and my wife recently moved into our new home and the electrical wiring through out was a lot worse than I anticipated that it would be. And so me and my wife are both wondering if anyone knows of any good electricians in Hamilton that they would recommend.

  26. My brother in-law is an electrician and he has been teaching me things about it ever since he found out that I am interested in it. I have a long ways to go, but I think that I could become a fairly good electrician. It would be an awesome hobby and it is a good skill to get under my belt.

  27. Being an electrician is really complex. My dad built our house and he did all the electrical work in it. I was really surprised that he didn't hire an electrical contractor to help, but everything seems to be working just fine. http://electriciankc.com/

  28. So there is no requirement for ground up or ground down? I guess it just comes down to personal preference. I like ground down, most electrical devices have that as the bottom anyways.

  31. I think it's just a matter of which it easiest for the situation. That is what I have always done. If it's easier to ground up then I ground up, and vice versa. I think if it gets the job done then there's no dispute.

  33. Well this has been the argument since a ground was first put in a plug. Ground on top or on bottom? I prefer on bottom. It is just to fit most electrical plugs. The funny thing is that it doesn't really matter. It works either way.

  34. I have to admit, I don't the difference. Grounding is grounding to me, I've never heard of up or down. Of course, I don't do too much with electricity, I leave that to the electrician, who I trust to ground themselves. Thiago | http://nepeanelectric.com

  37. My friend is a believer in saving money and doing things herself, so she is determined to fix anything electrical in her home. I tell her that she is taking a big risk by doing it herself and not letting a professional handle it. Fixing around with electricity is a hazard and it would be better to hire a company to help you than to try it yourself and get severely injured.

  39. It's so interesting that a common electrician practice started because of an incident at McDonald's. Thank you for clearing up whether a standing ground receptacle should be ground up or ground down. I run a restaurant and I had been hearing so many conflicting things. Now that I know that it's a matter of personal preference, I'll just have an electrician come in an tell me which is better for my establishment. Thanks again!

  43. My grandfather is an electrician and he is really good at what he does. My parents had our house re-modeled and my grandfather did all of the electric work. I never knew about this debate before though. I thought there would be a specific way set by some electrician agency on what is the right thing to do.

  44. I am going to be building a house from the ground up. I will be needing to hire myself an electrician for this.

  45. That's actually really interesting. I never knew where that all started but I have heard a lot of people say to do it both ways. I've always wondered which way was better. When you are doing your work which way do you prefer to do the grounding?

  46. This is why I would never be an electrician. I know I would forget which was ground up and which was ground down. I think electricity can be really difficult to understand. You can see in this example of how perfect you must be when working with the wiring of a building.

  48. I have a lot of respect for electricians because I saw what they have to do on a daily basis. We recently built a house and we needed to get some electrical work done and I watched the electrician work for a few minutes and it can be an extremely dangerous job. I have never really thought of how the electrical work gets done and now I have a general idea.

  49. It is stories like this one that make me wonder how true the situation like that was. It would seem strange for an electrical subject to come from a fast food incident, but truth is stranger then fiction. My dad taught my somethings about working with wire and such through out the years. I think that has helped me be able to help myself.

  52. I had no idea that there were testing guides that electricians could use for their jobs. That would make their job so much easier and would make it so they didn't have to know every specific component to every model or system out there. I wish I had something like this at my job to help me out.

  57. master electricians can offer work for both residential and commercial customers. Both of these types of electrical services take different skill sets and experience. It is important to work with a company that is fully licensed and insured. Looking further into the different types of services that are offered, any homeowner or business owner can hire an electrical company for a wide range of repairs.
