L.26 Provision for earthing
This clause only applies when the tool is in the configuration where it is directly connected to the mains
or a non-isolated source.
L.28 Creepage distances, clearances and distances through insulation
The clause of the standard is applicable except as follows:
L.28.1 Addition:
This subclause only applies when the tool is in the configuration where it is directly connected to the mains
or a non-isolated source. During the evaluation in this condition, battery packs are to be connected to the
tool. The tool is also evaluated with the battery pack removed if such removal can be accomplished
without the use of a tool.
L.28.101
Creepage distances and clearances shall not be less than values in millimetres shown in Table L.1. The
clearances specified do not apply to the air gap between the contacts of thermal controls, overload
protection devices, switches of micro-gap construction, and the like, or to the air gap between the
current-carrying members of such devices where the clearances vary with the movement of the contacts.
Creepages and clearances also do not apply to the construction of battery cells or the interconnections
between cells in a battery pack. The values specified in Table L.1 do not apply to cross-over points of
motor windings.
For parts having a hazardous voltage between them, the sum total of the measured distances between
each of these parts and their nearest accessible surface shall not be less than 1,5 mm clearance and 2,0
mm creepage.
