because earth doesn't catch fire or electricity
The term 'house earthing' is used in the electrical wiring of a structure in order to ground the house against electrical leakage which can cause increased power usage and the possibilty of safety concerns involving electrical shock.
The chassis of electrical equipment is typically connected to the Earth through the Ground (Earth) terminal of the electrical outlet. This is why building wiring should (or must, in many areas) include an on-site Earth ground connection. Earthing of equipment chassis is a safety measure taken to help prevent electrical shock in the event of an insulation failure or a short circuit. If there were no chassis-ground connection, a hot wire which accidentally comes in contact with the chassis could cause the user to get a serious shock. If there's no Earth connection available, use a GFCI outlet to help prevent electrocution.

Yes, there is a risk of hot/ground reverse in the electrical wiring of this building, which can pose a safety hazard.
An open ground outlet indicates that the electrical wiring in a building may not be properly grounded, which can pose a safety hazard by increasing the risk of electrical shock or fire.
In general, it's everything that starts at the meter base and goes to the lights or electrical outlets. House wiring is typically behind walls, under floors or in the attic so it's the wiring that you don't typically see, but use it every day.
When installing electrical wiring outside of electrical conduit, it is important to consider safety measures such as using weatherproof materials, grounding the wiring properly, protecting the wiring from physical damage, and following local building codes and regulations.

Electrical wiring standards are defined by your local municipal building Inspector. Wiring standards will vary depending on your local ordinances. Just contact your local building inspector for the requirements in your area.
These types of vehicles will have their own regulations as to their wiring, as governed by the manufacturer of the equipment. The building that the vehicles are stored in will be under the electrical code mandate.
The advantages of using Romex conduit for electrical wiring installations include easier installation, protection of wires from damage, and compliance with building codes.
