one of those "pin halfway out of the grenade" mornings......


~~Please excuse the mess. Sig under construction~~

well, i needed to measure working loads on this panel, so.....
pulled off the cover, looked at this, and was glad for PPE.

notice the cardboard? that is all that is separating the lugs feeding the
panel from the deadfront.

panel is a square dork with the locking cams that go behind the deadfront
instead of the lip on the can.... the bottom ones were missing, thank god.

'cause if you notice, one of the screws holding the deadfront to the panel
guts is missing, so if you tighten the screws down on the bottom, it gives
you the chance to pull the deadfront away from the guts, possibly releasing
the cardboard to fall down, causing bad things to happen, if not right then,
when the next person undoes the locking cams on the bottom of the cover,
allowing the deadfront to relax, and contact the feeder lugs.

just one of those things to make you pause, when you are about to pull off
a panel cover you've never been in before... this isn't the first time i've found
this type of stuff in this facility.

there's a bucket hole in a 480 mcc that has cardboard replacing the back of the
compartment right in front of the 600 amp bus..... :-(

new policy here in this place.

screw ppe. i'm downing the gear before opening anything up here the first time.

after i've been thru something, i'll put a label on the cover saying
Opened xx/xx/12 with my name and phone number on it.

when going thru a minefield, it's nice to know whose footprints those are
in the snow in front of you.

Why are the lugs so close to the deadfront anyhow? Did someone drill and tap the buss and add their own lugs?

Usually what I see are the panel cover screws that are rubbing the service wire insulation. Of course you see it after you pull the cover off and count your blessings it didn't actually pierce the wire yet....

Some guys need to get better at bending wire into place or using the zipties with screw holes in them.

We have a panel at my Temple that also has a cardboard insulator - someone in the past butchered single-phase guts into the bottom half of a 3-phase Frank Adams panel. Cardboard right behind the galvanized tin riveted onto the deadfront, right over the lugs... When we get a chance, the whole panel is going away and the circuits will be re-routed into a panel on the other side of the wall.
