How much voltage is found in one hot line?

The question focuses on the voltage typically found in a hot line of an electrical system. In standard electrical systems, particularly in North America, household circuits often have a voltage of 120 volts in the hot line. This is a critical component to understand as it relates to safety and functionality in commercial food equipment.

When we consider the choices provided, the voltage in one hot line usually refers to the standard voltage levels. The option stating "None" is not accurate because it implies that there is no measurable voltage within a hot line, which contradicts the basics of electrical wiring. A hot line is designed to carry current and typically presents a voltage.

In most residential and light commercial settings, the standard voltage found in one hot line is 120 volts. This voltage is crucial for the operation of many electrical devices and appliances, particularly in kitchens and service settings where commercial food equipment operates. Having an understanding of this voltage level aids technicians in ensuring proper installation and troubleshooting practices while maintaining safety standards.

Thus, the voltage found in a typical hot line is indeed around 120 volts, making it essential for anyone working in the field to be aware of these standards for effective and safe electrical service and repair.
