When calculating show window as per nec 220.43. Is there a 125% demand on the calculation of the show windows?
 
Let me ask you, do you think the lights in a show window will likely be energized for more than 3 hours straight? If yes, that makes it a continuous load. And the answer to your question is yes.
 
I know what a continuous load is. No where in that article does it state to calculate at 125% thats why i asked. Ps continous load is not just on for 3 hours straight but thank you

First off, I wasn't being sarcastic or condescending, if it cam across that way. The examples in the annex do show applying the 125%. But what does your second sentence mean? The code says 3 or more hours. I teach my students that any interruption is not continuous.

Its all good I thought you were being sarcastic, my bad. What i was saying is that a continuous load should its maximum current load for 3 hours or more not just something that runs for 3 hours. With that being said thank you for the input i just wasn’t seeing those lights identified as continuous load . Good day friend
