Inside cover Required?

[rromoser]

I don't understand the quickly part of needing to turn off power. This is a safety device to isolate the 240v power from the unit before servicing it. I know of nobody who can outdraw electricity and pull a disconnect before the circuit completes through ones self. That tech needs to have 240v GFCI breakers on the units he's servicing.

Randall,

That is incorrect, the disconnect to the outside AC unit does not need to be 1.) GFCI protected and 2.) does not have to be fused or circuit breakered at the location of the unit outside......however it does have to be able to be disconnected for service.....which is done my a standard non-fused pull-out.

The OCPD is located back at the distribution panel and will serve the purpose needed for being that QUICK DRAW for the electical current.

Now it is very common to lock out a disconnect and it fine.....again tie wrap is used most commonly in my area.
