The Single-Line Diagram 

Thank you Thomas.

Saweeet! Thank you for your efforts and the awesome link for Selective Coordination information.

Thanks to getting knowledge about step by step procedures in single line diagram and many links to power system including the important terminologies of electrical system.

Thanks for putting this out here, we are putting together a one line drawing of our 3 phase 208 wye boat for the coast guard, and really haven’t found a more complete explanation of one line drawings. Wish us luck. ✌🏽

Great video! I love the idea of having a physically isolated breaker or transformer integral breaker before the secondary panel to reduce incident energy. I wonder what the cost of this plus a MLO panel is vs a panel with a main breaker. Safety is almost always worth the cost increase, I just wonder if it could be justified across an entire facility.

Sometimes(most of the times) at a power plant outage, all the diagrams are in flux, they may be 'somewhat' accurate but are subject to markups(as-builts). Can be confusing but just need to use common sense and be aware. Those outages are always a race against time to get the system going based on a deadline.

Thanks, very usefull
