If 3 phase 240 is used to power a piece of equipment that should be powered by 1 phase 240 will it damage the equipment?

As only one phase of a 3-phase supply can ever be properly connected to a piece of 1-phase equipment, such as a motor or whatever, no damage will result if that connection is done correctly.
As most household 1-phase ac power is derived from power generated and distributed as 3-phase power, this question may just be an exam question designed to catch out students who don't really know what they are talking about...

If 1 phase 240 is used to power a piece of equipment that should be powered by 3 phase 240 will it damage the equipment?
odds are it is a motor and that would be yes
Can you plug a single phase piece of catering equipment into a triple phase socket without dire consequences?
Without a proper converter, no you can not. The consequences would be damage to the equipment, wireing, fire, and possible injury or death. Don't do it. Have a single phase outlet installed.
In three phase current the phase to phase is connected what will happen?
This is called a "line-to-line" short and it will trip either the main circuit breaker in the panel, or the fuse protecting the panel. It might also result in personal injury if someone is in contact with the equipment when the short happens. Equipment or damage is also possible.
What are the advantages of using a three-phase system over a single phase system?
For the info. of everybody..... the 3-phase system is definitely use in large commercial & industrial plant that uses large equipment/apparatus, like motors powered by more than 230v supply. However, single-phase system was commonly used in residential, which uses 230V or 110V equipment/apparatus, also considered as light load....

Does a two phase heater need a two phase thermostat?
Most electrical equipment are either designed to work on Single phase (two wires) or Three Phase (three or four wires). Two phase equipment are non existent today. A single phase heater will require a single phase thermostat while a three phase heater will require a three phase thermostat.
Will three phase power damage single phase appliances?
If you plug a single phase appliance into a three phase power supply, then you will be using single phase power. It does not matter if you are delta connected, AB, BC, or CA, or if you are wye connected, AN, BN, or CN. Yes, if there was "a problem", you would trip the supply. Question, however, is what do you define as "a problem"? Three phase power is intended to supply three phase appliances. Connecting a single phase appliance to three phase power is inconsistent with the objective, and such connection must have been performed by some kind of "jury-rigging". If you pull more than the trip current on any one phase, the supply should trip. If a malfunction in the single phase application, however, were to result in fault current that is lower than the trip current, you might not trip, and you might create damage and/or a fire. There is nothing wrong with building a branch circuit that feed a single phase load from one phase of a three phase source. You just need to provide the correct protection for that intended load.
Where would I find phase converter equipment being used?
Phase converter equipment can be used in a generator. They can help provide electric power. Phase converter equipment is used to run computers, pumps, etc. There is quite a bit of information online at www.phase-a-matic.com.
How does a 3 phase induction motor continue to run during single phasing?
The magnetic field produced by the powered phase induces a voltage in the other two phases. Such a setup has no rotating field to start the motor, but it will continue to run if already turning. The power output will be less than normal. This is the principle used in so-called rotary converters, used to run 3-phase equipment from a single phase source.
Where are three phase transformer systems used?
Any where that a three phase supply distribution is needed to operate three phase equipment.
What equipment is used to check phase rotation?
A phase rotation meter. Or a small three phase motor can be wired up and its rotation observed.
What is the advantages and disadvantages of single phase and three phase?
Single phase inherently requires less equipment (it's cheaper). Three phase motors are more efficient than single phase.
Can you buy a converter to connect to 240 single phase and convert it to 208 3 phase for electric grill?
If you mean by a converter, a transformer, to change the voltages then yes 240 volts can be transformed with a step down transformer from 240 volts to 208 volts in a single phase system. To answer the question single phase can not be converted to three phase without additional expensive equipment. One piece of equipment that will do it is a variable frequency drive. Another piece of equipment is a roto-phase. Either of these pieces of equipment would probably cost more than the grill you are trying to supply a voltage to.
