Identify the Problem and Solution

What happens here

The video introduces the problem: a wooden joist is located directly where a light fixture needs to be installed, preventing the use of a standard-depth electrical box. The Journeyman Electrician then presents the solution: a 'pancake box' (also known as a shallow or flat electrical box). He explains that this type of box is designed for situations where there isn't much depth between the drywall and an obstruction like a joist.

Goal: Understand the necessity and utility of a pancake box for shallow ceiling installations.
