I don't see in NECA MLU a labor section to install a 4000A service switch in an existing switchgear line up. Actually an existing 4000a is coming out and new one installed.

Ok, does anyone know what is accurate for the labor for this install?
Are you saying you'll replace an existing 4000A ?
is it just a main, or does it have subs?
How many parallel feeds?
How many subs out (if any)
All conduits come from the bottom? how many from top, sideways, backways, etc?(you know the size of the existing will not much the new one).
Will the wires be long enough to terminate into the new one without polaris taps?
If it's a main with everything from bottom and wires long enough I would go with 36 hrs.

I'm not sure how it works in other states but here in Northern CA PG&E mandates anything over 2000A be busduct.

Is this a bolted pressure switch or a circuit breaker?
Bus to bus connection?
And bus modifications necessary.
Adding ground fault protection?
Lost of variables, we do maybe 10-20 of these a year typically we allow 4 men 16 hours overtime plus two men 16 hours straight time. Plus about 25%-50% adder for doing the work.

Bolted pressure switch w/GDP. Why does the GDP matter when it comes to installing the switch? Thanks
