I have been looking through NEC, especially section to see if there are any references to calculations needed for inputting values in the schedules.
Is there a good reference regarding formulas needed in order to calculate these values?? I'm not seeing anything to refer to unless I'm over looking. Thanks in advance!! Location Illinois. The loads come from the Article load calculations that should have been done as part of the design process.
I am not sure I understand the question. But here is my stab at provding you an answer. If a single phase, line-neutral load is connected to Phase A, then you put the total load taken up by that item in the Phase A column. For example, if you have a volt, 20 amp circuit that supplies five general purpose receptacles, then you put VA 5 receptacles at VA each equals VA in the Phase A column. If a single phase, line-line load is connected between Phases A and B, then you put half the load into each column.
For a three phase load, you split the load three ways. For example, if you have a volt, 20 HP motor, you first look at table If that does not give you a starting point for your calculation process, can you tell me what you are trying to figure out?
One important point: always do the calculations in terms of VA, not in terms of amps. If you want to figure out the load, in amps, on any given phase, do that part of the calculation only after you have added up everything in terms of VA.
This is particularly important if you have a mix of single phase loads and three phase loads. Location Ohio. RJK42 said:.
That answeres alot.Schedule of load preparation is essential and a basic calculation for electrical engineers. In this process the proper sizing of conductors, overload protection and conduits are determined. While there are different methods doing an electrical design but there is only one thing that cannot be altered code requirements must be followed. This example emphasized the procedure rather than mimicking the actual loads of a residential unit.

In this example the voltage drop and short circuit calculation is not included. The system voltage of this example is VAC, 60 Hz. O 1 VA 10 1, 8. O 1 VA 12 2, 9. Schedule of Loads Schedule of loads are just a summary of data to easily identify and facilitate the necessary values and equipment rating to be used in any electrical installation. Any data given in the schedule of loads were backed by calculation based on a well settled electrical principles and code requirements.
Note: since the breaker is 30 Ampere, we could increase the cable size to 5. References: 1. National Electrical Code Handbook 2.

Panel Schedule Templates
Next Post.You can formulate a panel schedule easily by using this free panel schedule template. Panel schedule is something that displays information about the panel, the circuits connected to a panel and the load summary on panel etc. It is a useful tool to measure circuit load on a panel when planning a project. It plays an important role in taking care of electric supply to a building or house. Maintaining of fluent electric supply in required quantity is important to avoid short circuits and other likely issues that is why it is best to produce a panel schedule with assistance of panel schedule template.
A panel can be described as a collection of branch circuits feeding system loads and project managers use panel schedule to measure the exact amount of voltages in a panel. A panel schedule template provides a user friendly graphical interface with various suitable default values and constructive built in electrical related information to make get a perfect panel schedule as per your desires.
An elegantly designed panel schedule template is available here for you which it totally free to download without any extra requirement. Download it to your computer and edit in Microsoft excel to get better outcomes.Panel schedules are an important aspect of programming. Keeping track of the timings, names, and appointments, the entire exercise can be confusing, however if you have ready-made panel schedule samples at your disposal, then not so much.

Apart from these, there are residential electrical panel schedule templates as well as the panel Board schedule template that is very popular among the professionals in the electrical industry. These documents are well-spaced out and contain fields such as panel names, locations, etc. They are easily available on the Internet, it is downloadable and fully customizable.
Define a Panel Schedule. A panel schedule is a diagram that is used when planning a project, mainly by electricians and engineers. It is used to display information regarding all the circuits connected along with their respective loads.
This needs to be done so that the circuit loads can be measured and changed according to the power source. What is the importance of a Panel Schedule? A panel schedule helps electricians and engineers to display details regarding a panel that connects the circuit to their corresponding loads. It is one of the most essential designs that any project needs, especially when dealing with electrical appliances.
What are the components of a Panel Schedule? A panel schedule displays information about the panel, the circuits connected to it and the amount of current they carry. What is a Consumer Panel? What are the uses of a Panel Schedule?Before generating panel schedules, you should set up load classifications, demand factors, and panel schedule templates.
These items should be a part of the default electrical project. In Revitthe process of customizing and creating panel schedules is as follows. Set up load classifications. See Load Classifications.
Set up demand factors. See Demand Factors. Assign demand factors to load classifications. Assign load classification to family connectors.
Format the panel schedule templates. See Editing Panel Schedule Templates. Create panel schedules. See Creating Panel Schedules. View panel schedules. See Project Browser.

However, it is one thing that most of all should know about while revamping or rebuilding our houses or while moving to a new place and taking care of the electric supply of the house. Even while you have to take care and keep a check on the electric supply and the circuits attached to a panel.
I remember we first notice this when we were moving to a new house. A lot of electricity fluctuation and dim lights became a norm. Moreover, most of our appliances also would not work how they should have. This caused a lot of trouble for us, since we had recently shifted to a new place and hardly knew anyone in the neighborhood.
Moreover, as I was moving to this new place with a bunch of family members who actually had no idea about any such thing. For at least a month, we were stuck and struggling and adjusting with the constant power failures, and voltage fluctuation.
Until we sought help from an engineer living next door.

The trick was simple. We had to keep a panel schedule and make sure that the electric supply of the house was fine. Panel schedule is basically a sheet that displays various important information about the electric circulation of a place.
Typically, a panel schedule shows information about the electric panel itself, the circuits attached to it and the amount of electricity that they use. A panel schedule in general has four parts, a header, a circuit table, a load summary and a footer. Through these parts, the most intricate details about the electricity supply of a house or a place can be provided and be maintained to a panel schedule user.
