Electrical Panel Load Calculation Software

The purpose of the residential electrical load calculation is to accurately determine the size of the electrical service base upon the electrical equipment that will be installed.

Electrical panel load calculation software.

He was a journeyman electrician master electrician and electrical contractor. We have an all electric house which currently has a 200 amp service. Mike holt worked his way up through the electrical trade from apprentice electrician through electrical contractor to become one of the most recognized experts in the world as it relates to electrical power installations. Then with the selection of panel sizing the panels can be determined.

Loadcalc panel schedule performs load calculations for residential commercial and industrial occupancies. Developed for electrical designers and engineers the power panel schedule software combines a graphical user interface and the intelligence of etap to easily layout design calculate and analyze low and medium voltage panel load schedules and distribution panel boards. Commercial electrical load calculations. Flashworks takes the work out of the calculation process.

When we use your calculator it tells us our service should be larger than 200 amps. In 1974 mike realized there was a need for quality electrical training and opened mike holt. Loadcalc panel schedule new 2020 nec version. Soof the phase currents given under load details on main panel and feeder wise electrical load on main panel do not appear correct when using 3 phase loads.

Demand factoring neutral loads panel schedules panel directory reports and more all in compliance with the most current national electrical code requirements. Total electrical capacity of an electrical service is measured in amperage amps. Knowing how to correctly size loads in commercial applications is an essential skill for electricians. A click of the mouse and the calculation is complete and displayed on the screen.

When speaking about a building s electrical panel the load is comprised of the dozen or so branch circuits leading from the panel to various parts of the building. In very old homes with knob and tube wiring and screw in fuses you may find the original electrical service delivers 30 amps slightly newer homes built before 1960 may have 60 amp service. In electrical engineering a circuit consists of a voltage source and a load i e. The nec covers commercial calculations in.

Calculations can be performed as fast as one can enter the information into the predesigned entry screens. In many homes built after 1960 or upgraded older homes 100 amps is the standard service size. By my reckoning this should be 7a per phase or perhaps i m missing something. The national electrical codes are the basis of making sure the electrical service is sized properly and installed correctly.

But an electrician has told us we are approaching the upper limit of our service. The part of the circuit that draws power from the source.
