percussion clef question

[Menu Jacques]

Hello folks,

I’ve never created scores for percussion, so may question is a newbie one: can the percussion clef be used in any context, without changing the number of lines in the staff?

And if so, it the output for the example below the right one?

Thanks for your help!
