The regulations differ a bit nationally and for what the
equipment might be. ( Industrie, office, medical, aircraft, military )

you have to check it.

A general clearance of  3 mm between L and N and PE for 230V and class I.
                                8 mm between L and secondary or metal case class II

The test current for PE is 20A. The track width should withstand the fuse -
current x 2.1
for half an hour. ( overload condition ) . That means, the temperature
raise should not be
more then 40 Kelvin for that current. ( There are tables and calculators for
current --> temperature. )

Hope it helps,

Georg
