I have a Square D QOC series main panel (QOC 40MW225). I'd like to add service entrance barriers to this panel - the plastic covers which protect from accidental contact with the connection lugs of the main service entrance cable. I take it that newer panels these days typically come with a barrier, but mine is old enough not to have one.
It seems like the Square D PKSB1HA might be the correct product for this panel, but I'd like to confirm that. e.g., some marketing text for this product says:
Compatible in 100 through 225 amp Homeline & QO S0 series panels
Retrofittable to most existing Square D load centers
Is that the correct barrier or is there an alternative?
