84 should be mounted on the drivers side floor
Substations may contain uninsulated high-voltage lines, busbars, and other equipment. Although this live equipment is mounted at a safe distance from trained personnel, those unaware of the hazards may approach the live equipment without realising that the voltages are high enough to break down the insulation of the air if they should approach within the safe distance limits, with lethal results.
It depends on how high the ceiling is.
48 inches high from the floor Answer: This height can vary depending on how tall a person is. Generally speaking, a towel rack should be about chest height for a bath towel rack mounted near a shower. For a hand towel rack that is mounted next to a sink, normally it should be about 15-20" above the cabinet.

80 inches
A person should a clothes hook high enough so they can reach it. The hook should also be high enough so the clothes will not reach the floor.
Home pool cue racks tend to be mounted lower than those in pubs and bars. In fact, pool cue stands on the floor are quite common. So, there is no minimum for home racks. The lowest section of bar cue racks tends to be 30 to 40 inches from the floor.
It depends upon local code, but for Colorado, I found this document: http://www.dora.state.co.us/electrical/forms/HomeownerPermits.pdf It says: The main service equipment / panel shall be mounted either outside or inside the dwelling as near as possible to the point of entrance of the service conductors to the building. All service equipment and electrical panels shall have a clear area 30" wide and 36" deep in front of the equipment. This clear area must extend from the floor to ceiling with no intrusions from other equipment, cabinets, counters, appliances, pipes, etc. Service equipment/panels are not allowed in a clothes closet or bathroom. I thought I had read that the panel should be at centered least 36" above the floor, but can't find that. Basically I think the idea is that the panel be high enough that most people can easily look at it and used from a standing position. I'll update this answer further, if I find out more information.
