GFCI Circuit Protection for Shed Wiring

How to Install The Correct Size GFCI Circuit Breaker and Wiring for a Shed: Protect the individual circuits that will be readily accessible with a GFCI device, outlet or circuit breaker.
Shed Electrical Circuits and GFCI Requirements
Electrical Question: I have a sub-panel in my home utility shed. I have a 30 amp circuit breaker in that panel that I want to run 12-2 UF from, underground, to another shed. I want to feed 4 outlets and a ceiling fan in the second shed. I want to run first to a 20 amp GFCI outlet (that I already have), then through the other 3 outlets and end at the ceiling fan. Somebody said I have to have a 30 amp GFCI, but I will never pull even 20 on this circuit (the fan is .5 and I will never have more than 5 other devices plugged in, none of them high amp). Can I use the 20 a GFCI on the 30 a circuit?

Thanks for your electrical question Erasmus.
Electrical Wiring for a Shed
Installing The Correct Size GFCI Circuit Breaker
- You cannot protect a 30 amp circuit with a 20 amp GFCI outlet.
- Circuit wiring, circuit breaker and the outlets must be sized properly to maintain circuit integrity.
- Protect the individual circuits that will be readily accessible with a GFCI device, outlet or circuit breaker.
