Properly maintained panel schedules are crucial for ensuring the safety of service personnel, contractors, and equipment. In an emergency, accurate and up-to-date panel schedules can save valuable time and ensure the safety of those working on or near the equipment.
Not only do they assist in determining which equipment is powered by which breaker, but they also provide a reference point for locking and tagging out for safety. Additionally, appropriate labeling standards are essential for identifying the correct apparatus to be de-powered, particularly in situations where there are multiple breakers controlling identical machinery or when personnel are not familiar with the infrastructure.
What is a panelboard schedule?
A panelboard schedule is a document that provides detailed information about the electrical panelboard and its components. It typically includes information such as the panelboard’s location, the number and type of circuits, the amperage rating of each circuit, and the load on each circuit. It also includes information about the breakers or fuses that protect each circuit, as well as their ratings and trip settings.
The panel schedule is an important safety tool that provides a clear and concise reference of the electrical distribution system, it is used to identify the electrical power source for a specific equipment, to properly maintain the system, to troubleshoot issues, and to plan for future upgrades and maintenance. This document is usually found in the main electrical room or near the panelboard and it is updated regularly to reflect any changes in the electrical distribution system.
Panel Schedule Templates
Panel Schedule Templates are valuable tools used in electrical engineering and construction projects to document and organize information about electrical panels and their corresponding circuits. These templates provide a structured format for recording essential details about the electrical distribution system within a building or facility. Panel Schedule Templates assist electrical engineers, electricians, or project managers in designing, documenting, and maintaining electrical systems effectively.
Panel Schedule Templates are crucial for organizing and managing electrical systems in residential, commercial, or industrial settings. By utilizing these templates, electrical professionals can maintain accurate records of panel configurations, circuit details, and load information. Panel schedules help ensure compliance with electrical codes and regulations, facilitate troubleshooting and maintenance activities, and support effective communication among project stakeholders. Whether used in the design phase, during construction, or for ongoing maintenance purposes, Panel Schedule Templates provide a standardized and efficient approach to documenting and managing electrical panels and circuits.

For each circuit, calculate the load (in amps) based on the electrical specifications of the equipment connected to that circuit.
Organize the schedule
Organize the schedule in a logical and easy-to-read format, such as by panel location or circuit number.
Review and edit
Review the schedule for accuracy and completeness. Make any necessary corrections or additions.
Finalize the schedule
Once you have reviewed and edited the schedule, print it out or save it in a digital format. Make sure that the final version of the schedule is clear and legible.
Distribute the schedule
Distribute the schedule to all relevant parties, such as the building owner, the electrical contractor, and the local building department.
Types of electrical panel schedule
There are several types of electrical panel schedules that are commonly used in different types of projects. Some of the most common types include:
Branch Panel Schedule: This type of schedule lists all of the branch circuits in a building or facility and shows how they are connected to the main electrical panel. It includes information such as the circuit number, load calculations, and the location of each circuit.
Data Panel Schedule: This type of schedule is used in facilities that have a large number of data and communication lines. It shows the location and type of data cabling, as well as the equipment that it connects to.
Switchboard Panel Schedule: This type of schedule is used in large commercial or industrial facilities that have multiple switchboards. It shows the location and type of switchgear, as well as the circuits that are connected to each switchboard.
Lighting Panel Schedule: This type of schedule shows the location and type of lighting fixtures in a building or facility, as well as the circuits that power them. It also includes information about the type of lamp, the number of lamps, and the total power consumption of each fixture.

Important terms in a Panel Schedule
Absorbed Power: This refers to the amount of power (measured in watts) that is consumed by a piece of equipment or a circuit. It is calculated by multiplying the voltage and current of the circuit.
Efficiency: This refers to the ratio of the output power of a piece of equipment or a circuit to the input power. It is usually expressed as a percentage and is a measure of how effectively the equipment or circuit is using the power it is consuming.
Non-Process Loads: These are loads that are not directly related to the production process of a facility, such as lighting and HVAC systems. They are considered to be separate from process loads, which are directly related to production.
Process Loads: These are loads that are directly related to the production process of a facility, such as machinery and equipment.
Power Factor: This refers to the ratio of the actual power (measured in watts) consumed by a piece of equipment or a circuit to the apparent power (measured in volt-amperes). It is a measure of how effectively the equipment or circuit is using the power it is consuming.
These terms are relevant to the panel schedule because they are used to calculate the load calculations and to determine the power needs of the equipment and circuits in a building or facility. It is important to include this information in the panel schedule so that the electrician can identify potential issues with power usage and take steps to address them.
