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.

A panel schedule is a document that lists all of the electrical panels, circuits, and equipment in a building or facility, and shows how they are connected to one another. Here are the steps to create a panel schedule:
Gather all necessary information
This includes the building plans, electrical drawings, and any other relevant documents. Make sure that you have the most current versions of these documents.
Create a template
Create a template for the panel schedule that includes all of the necessary information fields, such as panel location, circuit number, and load calculations.
Fill in the template
Using the information from the building plans and electrical drawings, fill in the template with the appropriate information for each panel and circuit.
Label the panels and circuits
Label each panel and circuit clearly and legibly, using a label maker or a pen. Make sure that the labels match the information in the template.
Add load calculations
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.
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.
Power Panel Schedule: This type of schedule is used in facilities that have large power loads, such as industrial plants or data centers. It shows the location and type of power equipment, as well as the circuits that are connected to each piece of equipment.
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.
The purpose of a panel schedule is to provide a detailed diagram of the electrical panel, including the location and type of circuits, the load calculations, and the equipment that is connected to each circuit. It is used to help electricians troubleshoot and maintain the electrical system and to ensure compliance with local and national regulations.
Panel schedules are used by electricians, electrical engineers, building owners, and local building departments. Electricians use them to identify the location and type of circuits, while engineers use them to design and assess the electrical system. Building owners use them to maintain the electrical system and comply with regulations, and building departments use them to ensure compliance with local and national codes.
Panel schedules are created by gathering all necessary information, such as building plans and electrical drawings. A template is then created and filled in with the appropriate information for each panel and circuit. The schedule is then reviewed, edited, and finalized before being distributed to all relevant parties.
