Load Calculation Question
Load Calculation Question
(OP)
Hi, newbie here. I'm trying to find a calculation to determine the load on a branch circuit. I looked at the National Electric Code Book, but I found a few different equations, I'm looking for a commercial application. Thanks in advance!!






RE: Load Calculation Question
What is the branch circuit, what is the breaker (or fuse) protecting the branch circuit, what is the load, etc., etc.?

Yes, there are rules of thumb (but of course, like any branch of engineering, that's all they are!).
For instance, depending upon the type of building, you can estimate the small power (i.e. single phase items plugged into socket outlets) at xx W/m2 (or W/ft2 if you're not in the UK where I work!).
You really do need to know more detail of the equipment and / or environment type being served.
