i think you just have to change the breaker from a 277 to a 120. 277 breakers are usually a 2 pole breaker and 120 is a single pole breaker.
NO.
277v is not two poles, it is one pole, one single pole breaker in a 480 volt 3 phase system (typically).
If you want 120 volts from a 277 volt source you need a step down transformer
277 volt to 120 volt , or 480/277 to 120/208 .

ReneYou can use a step-down transformer to convert 277V to 120V for an outlet. Make sure the transformer you choose is rated for the correct voltage and power requirements to safely convert the electrical supply. It's important to follow all safety precautions and consult a professional electrician if you're unsure about performing the installation.
277 Volts is derived from one phase of a 480 volt, 3 phase Wye wired transformer to the Neutral or grounded leg of the same transformer. Typically, 480 volt, 3 phase power is for commercial and Industrial use. If you have 120 volt power, you could, by means of boost Transformers, increase the voltage to 277 or something close. However, I not sure that you will achieve the same result as with the afore mentioned 480 volt, 3 phase.

Can you convert a 30 amp 120V RV receptacle into a normal 120V outlet?
No, you cannot directly convert a 30 amp 120V RV receptacle into a normal 120V outlet. They have different wiring configurations and power capacities. It is recommended to install a new standard 120V outlet for regular household use.
Can you convert a gas dryer 120V hookup to an electric dryer 240V hookup?
No, you cannot convert a gas dryer hookup to an electric dryer hookup. Gas dryers require a 120V outlet for power, while electric dryers need a 240V outlet for power. You would need to install a new 240V outlet specifically for the electric dryer.
What's wrong with a 240V outlet that tests at 277V?
A 240V outlet testing at 277V indicates an overvoltage issue. This could be due to a problem with the outlet wiring, poor electrical connections, or issues with the voltage supply. It is important to address this promptly to prevent damage to appliances or potential safety hazards.
Is there a way to install a 120V light on a 277V circuit?
No, it is not safe or recommended to install a 120V light on a 277V circuit. The voltage difference could damage the light fixture and pose a fire hazard. It is best to use a light fixture rated for the appropriate voltage.
Can SJ 300V rated wire be used for 277v light?
No, SJ type wire is not rated for 277V application. This wire is typically designed for lower voltage applications such as 120V or 240V. It is important to use wire with the appropriate voltage rating to ensure safety and compliance with electrical codes and standards.
