SLD design reference
(OP)
Hi everyone,
please help with reference regarding the step by step designing of single line diagram of a project.
Transformer sizing and selection, MCC s and branch circuits, and so on.
I am electrical engineer but not involved in this field before.
Any reference woulde be appreciated.

RE: SLD design reference
Here's my version of step by step:
1. Gather load infomation (some of this is guesstimating)
2. Design within limits of code to supply power to given loads.
3. Draw single line accordingly.
4. Wait for load information to change.
5. Redesign within limits of code to supply power to given loads.
6. Modify single line.
7. Wait for load information to change.
8. etc... etc... etc... this will never end until a building is demolished.
RE: SLD design reference
It is a new water treatment plant.
1. do you add up all loads or continuos loads? any extra? what does the code says? any rule of thumb? how to size transformer?
2. How to size breaker? what factor of ampacity of load for specific type of breaker or disconnector? How to size conductors?
3. how to size MCC? Do we need ground fault relay?
and a lot more questions
Thanks

You may want to hire a consulting engineer on this one!
