How is 4000a, 5000a(large) gear usually attached to a concrete pad? Anchor bolts etc.? Thanks.
Yes... With "et cetera" in there, is there really any other option? :huh:How is 4000a, 5000a(large) gear usually attached to a concrete pad? Anchor bolts etc.? Thanks.
IDK..that's why I'm asking. L brackets on the outside? I know when dist panels are mounted against a wall it's strut but was not sure when mounting to a concrete pad.Yes... With "et cetera" in there, is there really any other option? :huh:
I prefer anchor bolts from internal framework (some have anchor gussets in the section corners)... but depending on how the "guts" are arranged, may not be possible in all cases. External L brackets anchored to pad and gear is an option... continuous for aesthetics.IDK..that's why I'm asking. L brackets on the outside?

FWIW, I've not run into any spec'd embedded rails in my entire career.Does anyone (besides me) require this size gear to have 'mounting rails' imbedded in the concrete pad to aid in leveling and alignment?

If spec'ing rails, I would hope that includes the rails being securely braced to each other prior to pour. If the rails are off even a fraction of an inch, that could make the installer very frustrated. It's not exactly an easy task getting thousand plus pound equipment aligned to just one rail let alone two which are not perfectly parallel... :happysad:
That's what I meant earlier postI have seen them take a piece of angle iron after it is set in place and bolt it to the floor and then to the MCC, but not embedded in the concrete.

I have seen some older installs done that way, but have never seen it as a design spec on any job I have ever worked on.Does anyone (besides me) require this size gear to have 'mounting rails' imbedded in the concrete pad to aid in leveling and alignment?
I must be showing my age again.:ashamed1:I have seen some older installs done that way...
I think specs like that are just a victim of economics...engineering design by bean counters, not engineers.I must be showing my age again.:ashamed1:

Yes, I have done that several occasions. One where the existing gear had problems with racking style breakers due to the pad being so uneven.
