No, be it a single or three phase panel it is not safe on the ground. On a construction site the biggest fault of having panels close to the ground is having trucks and equipment running into or over them. Even temporary services used in construction have specification that have to be adhered to. The temporary service panel on individual floors on high rises construction site have to be mounted in an upright position. Even though they are portable and just off the floor by the width of a 2 x 4 they still have to be maintained in a safe condition for the people that use them.

Can you use this switch for three phase incoming and single phase outgoing?
No A intermediate switch can not be used to change three phase to single phase.
Is there any other wires colors used for grounded other than gray and white?
In industrial wiring 'three phase' green or bare copper is the norm for a ground. In home wiring 220/110 single phase, bare copper is the ground
Why would three phase be used instead of single phase?
Three phase electricity is used instead of single phase for industrial situations. Industries use three phase electricity instead of single phase to operate electric motors driving heavy machinery. Three phase electrical motors produce more power from the same amount of electricity and maintain steadier speed. Small portable motors such as drills and mixers use single phase. Motors used around the house are single phase. Motors used to run large industrial machines use three phase.
How do you wire a two-phase outlet for a stove?
Two-phase power is not generally available anywhere and three-phase is largely used for commercial and industrial applications.Residential power in the United States is single-phase, limited mostly to 240V at the service entrance panel as two legs of 120V each plus a common neutral.If that is what you're making reference to, please see the answers to the Related Questions shown below.
Can a single phase supply be used in a three phase supply?
Yes. This is often done in distribution boards.
Where is the neutral for 25kv ac single phase supply used for electric locomotives?
from ground
Would a row of washers with inverter drives connected to single phase panel board cost the same to run as it would set up on three phase panel board?
three phase would be cheaper for running motors are more efficient single phase is only used for small motors and loads where operating economy is not a concern
What does 110-220 refer to on my electrical panel?
It is a reference to let an electrician know what voltages can be applied to the distribution panel. Along with this data will be the amperage that the distribution panel can legally handle. It lets the electrician know that the distribution is to be used in North America and to be used on a single phase, split phase secondary supply.
How do you install a 110v receptacle from a 3 phase breaker box if there are no neutrals in the breaker box?
If there is no neutral available you cannot, unless you use an autotransformer and derive a neutral. A panel with no neutral is called a power panel and is used to supply 240 single and three phase loads.
Can you use this switch for three phase incoming and single phase outgoing?
No A intermediate switch can not be used to change three phase to single phase.
In ac single phase circuits what is the neutral for?
The neutral in single phase AC circuits is used as the common power return conductor for half phase operation. In a typical (US/Canada) 120/240 split phase system, generally used in residential applications, the voltage between neutral and either of the two hot conductors is 120 VAC, and the voltage between the two hot conductors is 240 VAC. Neutral is also grounded at the distribution panel, as well as at the utility distribution transformer, in order to limit the voltage of any conductor relative to ground, and also to be able to detect ground faults by sensing imbalance between neutral and hot currents. Note that this is not called two phase power. It is single phase, or split phase, and it comes from one center tapped transformer winding. The center tap is neutral.
What is single phase Controlled rectifier?
such a control rectifier that control or rectifier single phase. for that purpose we used SCR that is called single phase controlled rectifier.
Is there any other wires colors used for grounded other than gray and white?
In industrial wiring 'three phase' green or bare copper is the norm for a ground. In home wiring 220/110 single phase, bare copper is the ground
Why three phase meter is better than single phase meter?
A three-phase meter can be used for single phase while the reverse is not the case.

What are the drawback of single phase?
There are no drawbacks, single phase is used every day. It is the most commonly used electrical supply in the world today.
