with 3 phase lighting you do not have to use as large of wire and can use one neutral for every 3 current carrying conductors so it cut down on material costs ( as voltage increases current decreases)

The voltage 277 is the star-point voltage of a 480 volt three phase system. By using a 480 volt wye system you have the dual ability of running 480 volt three phase equipment along with 277 volt lighting. The side advantage is the ability of using the phase voltage to ground (neutral) 480 / 1.73 = 277 volts for general lighting of the building the 480 volt equipment is located in.
If the supply voltage is Vs and the equipment voltage is Va, then the equipment will work if Va = Vs (equation). But if Vs / Va = 220 / 120 (equation) the equipment will fail.
The unit of electrical potential is the volt. The volt was named for the Italian physicist Alessandro Volta.
No, the source voltage can not change to a lower voltage without using equipment to do so.
Using 400 volt equipment with a 440 volt power supply can potentially damage the equipment due to overvoltage, leading to overheating, insulation failure, or component burnout. It is crucial to check the equipment's voltage tolerance and specifications; some devices may allow for slight variations, but they typically need to be rated for the higher voltage. If unsure, it's best to consult the equipment manufacturer or a qualified electrician before proceeding.
While you can physically do this it violates the Electrical Code. 110 Volt and 220 Volt receptacles are required by the Electrical Code to be on separate breakers for safety reasons, this would put them on the same 220 Volt breaker.
For measuring electrical Current the electrical equipment used is Amphere meter. This equipment tells the current flow in the equipment.
If the supply voltage is Vs and the equipment voltage is Va, then the equipment will work if Va = Vs (equation). But if Vs / Va = 220 / 120 (equation) the equipment will fail.
Using a 240 Volt rated disconnect switch for a 480 Volt circuit breaker supply can lead to severe safety hazards and equipment failure. The disconnect switch may not be able to handle the higher voltage, resulting in insulation breakdown, arcing, or catastrophic failure. This could pose risks such as electrical shock, fire, or damage to connected equipment. Always ensure that electrical components are rated appropriately for the intended voltage to ensure safe operation.

Fluke offers electrical testers and electrical test equipment to name a couple. They even carry voltage detectors and volt alert. On their website they even offer demos and videos.
If your equipment is from North America then yes you will need an adapter as the Australians use a 230 volt system.
The Volt
No, you cannot directly connect a 110-volt circuit breaker to a 220-volt circuit. Circuit breakers are designed for specific voltage ratings, and using a 110-volt breaker on a 220-volt circuit can lead to improper operation, potential equipment damage, or safety hazards. If you need to work with a 220-volt circuit, you should use a breaker rated for that voltage. Always follow electrical codes and consult a qualified electrician for such modifications.

It shouldn't damage the equipment. But it will probably not work properly.
