Is a disconnect switch for a dryer required to be fused?

[oscarwong]

I am in California, dryer is 20KW. On the same note, does a water cooler's dsw need to be fused as well? From my understanding, only motors need to be fused? Thanks for any input.

If the circuit has overcurrent protection somewhere upstream then the disconnect does not need to be fused.

For residential cook tops and wall oven that are hard wired you still need a disconnect correct? If so do most of you just put a double pole switch next to the appliance?

What kind of dryer is this? 20KW is a lot of power.

What is a DSW?
Can you state the code section that requires motors to be fused?

Many questions here...this will get interesting.

Motors do not "NEED" to be fused. They need over current, short circuit, and ground fault protection. Multiple different ways to achieve that. Disconnect is a seperate requirement and can be done many different ways as well.

No disconnect is ever required to contain overcurrent protection, but often they do.
