As youcan see in the schematic to the left, there is one factory installedground (in solid borders) on the incoming side (bottom) and oneon the outgoing side (top). There is a dotted line around a secondground lug next to the solid ground lug. This indicates that theinstaller can field install one additional primary ground lug on theline and the load side. This additional primary lug can be found inlug kit ECMLK3225. This is a load center lug kit, but these samelugs are also used on many power mod modules.Above: Schematic found on wiring diagram for WT12400PUa Skinny mains have enough wire bend space to allow wiresizes of #4-300 kcmil.s May contain more/fewer lugs than installer requires.

This ground bar is not factoryinstalled since it is surrounded by a dotted line on the schematic.If there was a solid border around the secondary equipmentground, that would mean it was factory installed.

The number of ground lugs providedin a meter stack is equal to the number of neutral lugs plus one. Therefore, there is always one more ground lug than neutral lugs onevery meter stack, except in the case of house power combo modules (WC, WCL, WCT).Example: The unit to the left is a WMM32125RJ stack which has 3 meter positions. Thismeans this unit comes 3 neutral lugs and 4 ground lugsFactory installed ground luglocation for indoor ratedstacks (without “W” prefix”)Factory installed neutral luglocation for indoor ratedstacks (without “W” prefix”)Factory installed neutral luglocation for outdoor ratedstacks (“W” prefix”)Pro Tips:Almost all stacks have neutral andground locations above and belowthe cross bus. If an installer isrunning cables from the oppositeend, the neutral and ground lugscan be moved to the other side.The same extra lug provisions canbe used to double up on neutralsand grounds in a stack ifnecessary.Factory installed neutral luglocation for outdoor ratedstacks (“W” prefix”)Siemens Industry, Inc.
