Delve into the intricacies of power drawings in the context of a hotel area, with an exploration of power notes, fire alarm notes, the keynote legend, and wiring details. Discover how these drawings serve as a practical checklist ensuring all junction boxes are properly accounted for in the correct locations.
Key Insights
- The power drawings of a hotel area include elements such as power notes, fire alarm notes, and a keynote legend. They provide detailed wiring information, such as how all outlets in the hallways converge to an electrical box labeled 1L1, TAC 42.
- While the power drawings for common areas like hallways and IT closets are detailed, those for individual suites remain relatively generic. The specific electrical plans for each guest room would offer more in-depth wiring details.
- These power drawings not only serve as a blueprint for the electrical system but also act as a checklist. Each junction box for appliances, air conditioning systems, and other elements can be checked off to ensure they are correctly installed and accounted for.

Let's look at the power drawings for one of the hotel zones. You can see power notes, fire alarm notes, and a keynote legend. The wiring in the hallways is detailed, so I can see that all of these outlets come together and go to electrical box 1L1, TAC 42.
In this IT closet, the wiring goes to 1L4, TAC 1. However, when you look at the suites, you’ll notice that the information is still relatively generic at this point because the actual guest room electrical plans show more detailed wiring. But here, they indicate that we have junction boxes for the vertical air conditioner, dishwasher, cooktop, guest room, bathroom, and two for the appliances. The vertical air conditioning system is shown here.
It’s a relatively simple drawing, but it contains a lot of information. One advantage is that this drawing could be used as a checklist. Have we checked off all of these junction boxes in these spots? Feel free to spend a few more minutes reviewing this, and then we'll move on to our next drawing.
