How to fill out the Fault Current Forms online
Submitting the Fault Current Forms online is essential for ensuring that your electrical equipment installations comply with the necessary regulations. This guide will provide you with detailed instructions for each section of the form, helping users navigate it effortlessly.
Follow the steps to complete the Fault Current Forms efficiently.
- Press the ‘Get Form’ button to access the Fault Current Forms. Once clicked, the form will open, allowing you to begin filling it out.
- Provide your Electrical Contractor information, including your permit number, date, and the street address where the electrical equipment will be installed.
- Enter the city, state, and zip code for the installation site. This information is crucial for proper documentation and approval by the Building Inspection Department.
- Fill in the details regarding the electrical equipment installation. Specify the transformer KVA, impedance, and secondary voltage. Ensure that all entries are accurate to facilitate compliance with the National Electrical Code®.
- Indicate whether the system is fully rated or series rated. If applicable, remember to include component protection data sheets for series rated systems.
- Complete the conductor details, including the type of conductors (copper or aluminum), size, and lengths from the transformer to various points such as auxiliary gutters, service disconnects, and panels.
- Fill in the overcurrent device information, including ammeter ratings, interrupting ratings, and details regarding fuses or breakers. Make sure all fields are clear and accurate.
- Once you have completed all necessary sections, review the information you provided to ensure correctness.
- Save your changes, and upon final review, you may proceed to download, print, or share the form with the appropriate parties for approval.

Electrical faults can typically be divided into four main types: short circuits, ground faults, open circuits, and series circuits. Short circuits pose immediate dangers due to rapid increases in current. Ground faults can cause damage and safety hazards by providing alternate paths for the current. Open circuits interrupt flow completely, which can disrupt normal operations. Familiarity with these fault types is essential for managing fault current forms properly.

The following fault current calculation form must be completed and submitted prior to service approval. The most common fault is a single- phase to earth fault, which, in LV systems, can produce a higher fault current than a three-phase fault. Fault Current is defined in Part 2 of BS 7671 as, "A current resulting from a fault". The faults can be broadly classified into a) Shunt faults (short circuit) b) Series faults (open conductors). A fault current is an unintended surge of electrical current that bypasses its normal pathway in a circuit. Maximum current (first peak of the fault current). In this video we'll go over basic fault terms as well as the ways we can protect our power systems from unintended faults. There are two types of fault occurring in the power system, namely "symmetrical fault" and "unsymmetrical fault". Calculate your transformer's fault current with our calculator. The fault types are classified as: phase to ground, double phase to ground, three phase to ground, phase to phase, and three phase.
