Is this a backfed Square D panel? It’s kind of hard to figure out with some masking tape being in the way.
This is the second and last panel on the property.
Also, what does S/F mean on the manufacturer’s label?
Here’s what I’ve called out so far:
Improper and inadequate wiring of main lugs with double-tapped branch wire conductors.
Double-tapped circuit breaker.
The sheathing on the neutral conductors had indications of arcing or excessive heat. A qualified contractor should evaluate and repair or replace as necessary.
The sheathing on conductors underneath the main conductors showed signs of excessive heat.
A circuit label for the sub electrical distribution panel was missing, partial, illegible or inaccurate at the time of the inspection. Circuit breaker labels could not be read without taking the dead front off of the panel.
Defect at the clamp, connector, and bushing component at the electrical panel.
Improper termination of stranded sheathed aluminum conductors under the neutral lug, as well as in the main shutoff switch where some of the strands had been severed and not secured underneath the lugs.
Given the age the panel, the main CB, and the age of the other circuit breakers I would guess that the main was not factory installed. Those melted double tapped black conductors in the last photo are not properly protected by the 50 amp main. This thing is a mess.
Thanks anyways, and for letting me know that it’s backfed, Chris.
Thank you, Robert. Would you recommend that I write a comment about how the main circuit breaker does not meet the standards of modern residential homes? I would think that 90 or 100 amps is the minimum amount of ampacity needed for modern residential single-family dwellings.
Manufactured homes since 1976 are built to HUD standards, not to a building code or the NEC. Frequently MH’s with all gas appliances only had 50A service. But the panel is a mess, BTW, the backfed main may predate current holddown requirements, which makes things sticky if so.
