Implement the 'Always Buy Two' Rule

What happens here

The master electrician corrects his son, advising him to always buy two of any needed electrical component, even if only one is immediately required. He visually demonstrates this by showing two GFCI outlets. The rationale is explained: one part is for the current installation, and the second serves as a spare. This spare prevents time-consuming return trips to the supply house if the first part is faulty, lost, or if an additional one is unexpectedly needed on the job site. This practice is crucial for efficiency and avoiding wasted time.

Goal: Secure necessary components efficiently and prevent project downtime.
