Master Electrician Teaches his Son the Basics of 480-277 Volt Vs. 120-208 Volt Systems, Thoughts?

What happens here

The electrician notes that while 480/277V with step-down transformers is common, some smaller industrial facilities might directly receive 120/208 Volts from the utility company. In such cases, there is no need for an internal step-down transformer from 480V, as the utility provides the necessary lower voltage directly.

Goal: Understand variations in commercial electrical supply based on facility size and utility service.

wondering what they were, what they're transformers. >> Yeah, the gray those gray enclosures. >> Yeah. Yeah. Yeah. Every every place has to have that. Now some smaller industrial facilities will bring in 120 208 automatically from the utility company. Okay? Right? So there they don't have the ability to do 480. They're at a disadvantage. >> Okay? >> Right? Because their voltage is lower, their current is higher, the services need to be more beefier.
