The document outlines the requirements for electrical equipment installation compliance with the National Electrical Code® regarding short-circuit currents and interrupting ratings. It includes a form for electrical contractors to provide necessary information about transformers, conductors, and overcurrent devices, which must be submitted to the Building Inspection Department for approval before installation. The document emphasizes that it is for informational purposes only and does not replace official regulations.

Click ‘Get Form’ to open the plano fault current document in the editor.
Begin by entering your details as the Electrical Contractor, including your permit number and date at the top of the form.
Fill in the street address, city, state, and zip code where the electrical equipment installation will occur.
Provide information about the transformer: KVA rating, impedance percentage, and secondary voltage. This data is crucial for compliance with National Electrical Code® standards.
Indicate whether you are using a fully rated system or a series rated system by checking the appropriate box. If using a series rated system, ensure to attach component protection data sheets.
Complete sections regarding conductor types (copper or aluminum), sizes, lengths from transformer to auxiliary gutter, and service disconnects. Be thorough to avoid delays in approval.
Finally, sign and date the form at the bottom before submitting it back to the Building Inspection Department for approval.

Got questions?

We have answers to the most popular questions from our customers. If you can't find an answer to your question, please contact us.

What is meant by the term fault current?

Fault current is the abnormal current that flows in the circuit in the failure condition which will be several times larger in magnitude than the normal expected current.

Is fault current good or bad?

If a breaker or fuse isnt rated to handle the maximum available fault current it might see, it may not operate properly and its internal parts could fuse together or the device may blow up under the destructive stresses of a fault condition, which can cause serious injury and or property damage.

Which fault has the highest fault current?

Types of Electrical Faults Three-phase short-circuit: Occurs between one or more phases, generating the highest fault typically currents.

What is the fault level current?

Fault level is also referred to as fault current. It is the extra flow of electrical energy on a network during a short circuit or fault.

What is fault making current?

The prospective short-circuit current (PSCC), available fault current, or short-circuit making current is the highest electric current which can exist in a particular electrical system under short-circuit conditions. It is determined by the voltage and impedance of the supply system.

What is the allowable fault current?

Maximum available fault current, also known as available short-circuit current, is the highest amount of current that can flow through an electrical system during a short circuit event. This value is determined by several factors, including: The capacity and impedance of the utility power supply.

What is an example of a fault current?

In an electric power system, a fault or fault current is any abnormal electric current. For example, a short circuit is a fault in which a live wire touches a neutral or ground wire.

How to figure out fault current?

Fault current calculations are based on Ohms Law (V=IR). To determine the maximum current available at any given point in a distribution system, the equation is rearranged to solve for current (I=VR).
