Difference between high voltage and low voltage

Low and high voltage are common terms you will hear people talking about when it comes to voltage classifications.

As a homeowner, you must have come across voltage warnings on fixtures, wires, and electoral panels.

This article is going to discuss more on the difference bet high and low voltage.

If you are looking forward to establishing a new home, then it is advisable to reach out to a professional and experienced electrician to give you guidance on the best safety measures to take for your family.


Voltage is one of the methods of measuring and rating power lines and rating devices

• High voltage

High voltage is one that can cause harm or injury, according to international Electrotechnical commission, high voltage is one that is above 1,500 volts for direct current and 1000 volts for the case of alternating current. Read more here.

• Low voltage

According to the commission, it rates circuits that are between 120 and 1500 VDC for DC and between 50 and 1000 VAC for alternating current as low voltage.

How to adjust generator voltage

Learn how to adjust generator voltage as is needed. The generator can perform at various rates and that is useful to people.

Trust the design of the generator to produce all the electricity that is needed.

Conserve fuel and electric output by adjusting the performance of the generator. The controls might depend on the model and the manufacturer specifications.

The generator can work once the settings are changed. That could help the unit stay functional longer or produce more electricity when that is needed for the project.

The control panel is the place to look for adjusting the voltage. The unit will be rated to produce voltage at various levels. Pay heed to the voltage levels and what that will accomplish over time.

The adjustments are made and people will make the project work for many people. The instructions can direct people for the step changes. Trust the info going forward. Best Voltage Regulators for Generators on Amazon
