Filling out the LADBS NEC Standard Electrical Load Calculation form is a critical step for many when it comes to ensuring that electrical systems are both efficient and up to code. However, it’s easy to make mistakes if you're not careful. Here are nine common errors that are often spotted on these forms:

1. Not Reviewing Instructions: Skipping the form's guidelines is a common mistake. These instructions are designed to help filers understand each section's requirements, leading to fewer errors and omissions.

2. Incorrectly Calculating Square Footage: The total area of the living space must be accurately calculated. Errors in this section can lead to miscalculations in required load capacities.

3. Overlooking Small Appliances: Often, individuals forget to account for the electrical load of small appliances. Every electrical device adds to the total load, and neglecting these can result in underestimating the required electrical capacity.

4. Misidentifying Room Usage: Mislabeling rooms can affect the calculation, as different spaces have different load requirements. For example, kitchens and laundry rooms typically need more power than bedrooms.

5. Incorrect Allocation for HVAC Systems: Heating, Ventilation, and Air Conditioning (HVAC) systems are major components of the electrical load. Incorrectly estimating their requirements can either lead to an oversized system or one that fails to meet demands.

6. Overlooking the Total Number of Electrical Circuits: Each circuit contributes to the cumulative electrical load. Missing any circuit can result in an underestimation of the total load, leading to potential overloads.

7. Failing to Consider Future Needs: Electrical needs may increase over time. Failing to account for potential additions or modifications can result in a system that's unable to accommodate future requirements.

8. Mixing Up Units of Measurement: Confusing units of measurement, such as watts with kilowatts, can significantly impact the calculations. Accuracy in these details is crucial for the validity of the entire calculation.

9. Rushing Through the Form: Taking the time to carefully review and verify each entry before submission is essential. Rushed calculations are prone to errors, which can lead to rejections or the need for revisions.

To sidestep these mistakes, it's recommended to thoroughly review the form and its instructions, take your time, and double-check your work. When in doubt, consulting with a professional can provide additional assurance that your electrical load calculations are accurate and comply with all applicable standards and codes.
