Count up the violations/ hazards in this one. [Linked Image] From a home built in the mid fifties.

Assuming this is the service panel:
0) 110.12(C) broken strand in service cable grounded wire.
1) 230.70 No means to disconnect the two circuits (using wh, blk, grn cables) connected directly to service cable.
2) 230.82 Assume the two wh, blk, grn cables do not fall under this allowable connection before service disconnect.
3) 110.14(A) Assume the terminals the two wh, blk, grn cables connect to are not identified for more than one conductor.
4) 200.7(C)(1) requires the white wires connected to the red service wire to be reidentified with a color other than white, gray, or green.
5) 110.14(A) assume the lower right screw on the neutral bar is not identified for more than 1 conductor.
6) 312.5(A) grounding wire enters a hole that is not adequately closed
7) 312.5(C) the two wh, blk, grn cables are not secured to the cabinet
8) 240.51(B) there is evidence of overfusing, one or more 14 AWG or 12 AWG wires appear to be "protected" by a 30A fuse.
9) 240.54 requires type S fuses under these circumstances.
10) 250.24(B) it is unclear whether or not the neutral bar is bounded to the cabinet

It seems to me like applying a Code that's 50 years newer than the installation is not that much different than applying a Code that's 50 years older than the installation.

Does it meet 1905 Code?

It seems to me that the plastic sheathed cable is not 50 years old and the source of most of the violations. (Old romex would have reduced ground wire sizes.)

Did you all notice that the wires entering on the left appear to be SO CABLE!!

Not to mention that the white is lugged to the main AHEAD of the pullout fuses!!

Plus evidence of overheating on the lower-right hand pull out block's load connection.

Did anyone pull the meter out on this mess?!


Stupid should be painful.

And they appear to enter the lower left corner of the panel without any sort of bushing or other protection.

I often find systems here in which the original 1950s/60s insttallation was just fine, but the extensions and modifications to it in more recent times are the problem.

It looks to me as though this might be a similar sort of situation.

There don't appear to be any EGCs at all. Was that typical for the Romex of the period, or were they cut off and thrown away?

How on Earth did some hack install those SOs on the main lugs without getting lit up???

It's amazing what those hacks can get away with...for a while. Just slip on a pair of ordinary gloves, grab a screwdriver with a real plastic grip, and take on the world [Linked Image]. The insulation on those main conductors doesn't look too great. Might be some heating going on there also.

Trublu832: Can you tell us where those two SO's go?

The black and white wire looped into the left top switch / fuse carries has no fuse protection on it by the looks of it.

Also at the right no bushing used for the bare earth wire,

on the earth / neutral bar the wires are not terminated in an eye shaped way under the screws, but straight.

Typically you see these types of cables in older NZ installations from the 50's too.

Some cables are in very good condtions while other cables have very brittle insulation.


The product of rotation, excitation and flux produces electricty.

They look like solid conductors to me, which
means that it's not SO cable.

Look at how the wire holds its shape, and at the terminations on both the fuse block and the neutral bus.
