l. That is, the application
must be part of the FUS audit. Potting and coating requires recurring test.

Hi Jo
Hi John:
Clearance is defined as the shortest distance
between conductors in air.
Creepage is not an insulator, but the interface
between air and solid insulation. Creepage is
defined as the shortest distance between
conductors across the surface of the interposed
solid insulation
