Bolt-On Plug-In Panelboards: Understanding Voltage, Amps, and Main Breaker

What are the typical voltage and ampere ratings of a bolt-on plug-in panelboard? Does it include a main breaker?

Bolt-on plug-in panelboards are electrical distribution boards that have specific voltage and ampere ratings. Let's explore the typical ratings and features of a bolt-on plug-in panelboard.

Voltage Rating

The voltage rating of a bolt-on plug-in panelboard: Bolt-on plug-in panelboards usually have a voltage rating of 120 volts. This is the standard voltage for most residential and commercial buildings in the United States. The 120-volt rating ensures compatibility with common electrical devices and appliances.

Ampere Rating

The ampere rating of a bolt-on plug-in panelboard: The ampere rating of a bolt-on plug-in panelboard can vary depending on the specific model and purpose. Typically, these panelboards have an ampere rating that ranges from 15 to 200 amps. The ampere rating determines the electrical load capacity of the panelboard and dictates the maximum current that can safely flow through it.

Main Breaker

Presence of a main breaker in a bolt-on plug-in panelboard: Bolt-on plug-in panelboards usually come equipped with a main breaker or main disconnect switch. The main breaker serves as a safety mechanism by interrupting the power supply to the entire panelboard in case of overcurrent or short circuits. This helps protect the circuits and devices connected to the panelboard from damage. In conclusion, bolt-on plug-in panelboards are essential components of electrical distribution systems, providing a safe and efficient way to distribute power in buildings. Understanding the voltage, ampere ratings, and presence of a main breaker in a panelboard is crucial for ensuring proper electrical system functionality and safety.
