Cable drops across power conductors771 viewsMDU wiring. According to the building owner, this was "after" the upgrade, which was 'completed' in a single day. Wires run over the roof, even on top of the power drop conductors. Lock box has been broken into and wiring is a mess. Poor workmanship.
|
|
Another floodlight ground, MDU542 viewsMDU ground to a flood light fixture. The MDU rebuild crew decided that a floodlight over a carport on this MDU was a suitable place to run the ground wire. Note the copper ground strap wrapped around the painted electrical conduit.
|
|
A messy MDU723 viewsMDU wiring and security. On this building, the lock box has been abandoned and wiring left exposed on the outside of the building including filters and splitters. Very poor workmanship and security.
|
|
Rusty ground connection666 viewsGround strap on a very rusty power weatherhead. The installer had to work his way through the power conductors to make this very poor connection to an extremely rusted power mast. No apparent effort to clean or prepare the grounding surface. Too close to power conductors.
|
|
To the meter panel screw again.698 viewsGrounded to the center screw on a power panel. This connection interferes with access to the meter panel.
|
|
