Lamps do not produce electrical energy, they consume it.
The voltage at a lamp depends on the voltage of the local supply. That can be switched on or off to each individual map, or groups of lamps if required.
A light pole does not produce voltage, that is done at the utility's generation station. A light pole uses the standard voltage for whatever country you live in.
you can use two hot wire different phases with a double pole braker .
If the power requirement is 120 volts it will be connected to a single pole breaker rated at the amperage requirement of the air conditioner. If the voltage of the air conditioner is 240 volts, then a two pole breaker will be required.
30X240=7200
Light pole banners can be purchased at Downtown Decorations Inc. They provide a wide variety of light pole banners designs at very competitive pricing.
Answer for USA, Canada and countries running a 60 Hertz supply service.Sub stations have a variety of voltages depending on what systems they are connected to. At the sub station, the transmission voltage (might be 250,000 volts) is reduced to distribution voltage (might be 14,000 volts). The 14,000 volts is distributed through out the community and then the voltage is further reduces by pole transformers to a voltage (120/240 volts) that can be used by homes.

The light pole exerted the same force on the car that the car exerted on the light pole.
The electric furnace operates on 240 volts so a two pole breaker is needed.
Answer for USA, Canada and countries running a 60 Hz power supply service. 230 to 240 volts on any size two pole breaker on single phase installations. The voltage varies from location to location from different utility power companies.
A single pole breaker will be 120 volts. But to make 100% sure test it with a volt meter.
The light pole exerted the same force on the car that the car exerted on the light pole.
Correct
240 volts from the secondary side of the transformer to your house
