in the olden days, electrical engineers figured if you drop razorblade or pin between the receptacle and the plug, the metal will get in contact with the ground prong thus minimizing the chance of energizing a metal object. this is why most outlets in schools and hospitals are installed ' upside down". nowadays we install them 'downside up' to see a smiling face. ha ha.

JudyOutlets can be installed in either orientation, as long as they are properly grounded. Some electricians believe that placing the ground connector on top reduces the risk of objects falling on it. Ultimately, as long as the outlet is functioning properly and safely, the orientation is a matter of personal preference.

How do you plug in nema 6-20 into a North American 3 prong outlet?
You cannot plug a NEMA 6-20 plug, which has two hot wires and a ground wire, into a standard North American 3-prong outlet. The outlet is designed for 3-prong plugs with two hot wires and a neutral wire. You would need to install a NEMA 6-20 outlet with the appropriate wiring to accommodate the NEMA 6-20 plug.
Is it safe to plug in three prong appliances into a three prong wall outlet that has no ground to it?
No, it is not safe to plug in three-prong appliances into a three-prong outlet that lacks proper grounding. Without a ground wire, the appliances may not be protected against electrical faults, posing a risk of electric shock or fire. It is recommended to have an electrician install a grounded outlet to ensure safe operation.
Does the anatomical position change if the body is upside down?
If the body is upside down then it is no longer in the anatomical position. But no, it would not change.
Why are some outlets upside down?
Are you asking about a standard USA 120 Volt domestic wall socket containing a pair of outlets, where one outlet is positioned below the other one but looks upside down? If so, here goes:Each pair of socket outlets is made like this: a springy brass contact strip is fitted underneath the top outlet's left hole to connect it to the bottom outlet's left hole. Another springy brass contact strip is fitted underneath top outlet's right hole to connect it to the bottom outlet's right hole.One supply wire is connected to the left-hand contact strip and the other supply wire goes to the right hand contact strip.It doesn't actually matter which outlet hole is the hot and which is the neutral because the system allows you to put in an ungrounded plug either way round.If there are any ground holes these are positioned above and below each pair of the contacts described above, at the mid-way point. The top outlet's 3 holes then look like one triangle and the bottom outlet's 3 holes look like another triangle that is upside down to the top one!Another answerThe NEC does not specify what position a duplex receptacle is placed. However, some electrical plans, such as those for hospitals, may call that receptacles be placed with the ground hole facing up. This is to help prevent contact being made with the hot and neutral with something falling on a plug of a cord. The ground prong may help protect this from happening.The other school of thought is that with the ground hole facing down on a duplex receptacle if the plug of the cord has something fall on it the last blade to disengage would be the ground pin.Another explanationReason why "ground-down" is best/safer: the socket for the ground pin should be down because, if the plug starts to work its way out from weight on the cord, the first things to disconnect will be the power pins and that all-important ground pin will be the last to go, thereby providing its protection until no longer needed because the power pins have been disconnected first.
Is Uranus an upside down planet?
Yes, Uranus is often described as an "upside-down" planet because its rotational axis is tilted at about 98 degrees. This means that during its orbit around the Sun, Uranus appears to be rotating on its side.
