I opened up a CT cabinet recently and noticed that the neutrals (4 - 250MCM) from the utility landed in a 4 hole lug that was bolted to the inside bottom of the cabinet.
The neutrals that led from the cabinet to the service panel landed in a lug bolted to the inside back of the cabinet.
The continuity between the base of the cabinet and the back wall of the cabinet was several 2 inch strips of welding between the two parts of the cabinet. This seemed less than ideal to me.
All neutral current was passing via those welds.
Does this seem to be bad practice?
Would it not be "better" to have both of those 4 hole lugs on the same sheet of metal...either the bottom panel or the back panel?
Better yet, one lug that contained all of those neutrals or is the steel between the lugs sufficient?
