  1. MC, Metal Clad, & AC, Armored Cable are 2 different materials having different installation requirements & each has there own NEC article, AC art. 320, MC, art. 330. and both have the same limitation as NM in regards to protection from physical damage.
  2. Flexible cord cannot take the place of perm. wiring, as soon as the attachment plug is cut off & wired in, it becomes perm. wiring.
  3. Some Asian import reproduction switches are rather cheesy in construction, the terminal screws are tiny & most suitable for 16 AWG conductors, maybe 14 AWG, the vintage ones are quite robust in comparison.
  4. If it's bottom fed, it is foolish to have the lugs at the top, cleaner installation, less wasted wire, there is no right side unless a main breaker is operated vertically, then a bottom feed would violate NEC requirements, the SQ D main pictured operates side to side so there are no problems w/ it.
  5. There is a company called "Federal Pacific Transformer" is a off-shoot of FPE, (They bought the assets of the transformer div.) there is no reason to question the safety of the above company, BTW, the issues were limited to FPE "Stab-Lok" breakers not their fusible or other gear.
  6. Challenger Electrical Equipment Corp. did buy Federal Pacific Electric, but what did happen later I dunno. It is rather strange that the two most reviled names in electrical equipment were joined, Challenger was a successor to Zinsco. There are not too many who have good things to say about Zinsco or FPE.
  7. If the connectors are being used to pigtail AL to copper, there is a issue, most connectors were changed to CU to CU conductors only, there is plenty of space in the loadcenter for the splices so no problem w/ splices being there.
  8. Just for some additional info, the Walker gear later became part of the I-T-E Circuit Breaker Company, which later became I-T-E Imperial Corp, before being bought by Gould Inc in 1976, after a few more name changes it's now Siemens.
  9. If you look at the 2nd pic, there are 2 100A mains, 1 for each row. The taps off the main lugs is not kosher, remember there is NO overcurrent protection there.
  10. The twin breakers installed in the GE, Goverment Electric panel are not GE, & I doubt they are UL classified to be used in one. GE twin breakers are peculiar to GE & they will not fit a non-GE manufactured panel.
  11. Murray used to have a main breaker handle that was reverse of a "normal" model, it was shown in the OP's pics, but now that it has been replaced the "ON" position is down, meaning that it is now a violation of 240.81. 240.81 Indicating. Circuit breakers shall clearly indicate whether they are in the open ?off? or closed ?on? position. Where circuit breaker handles are operated vertically rather than rotationally or horizontally, the ?up? position of the handle shall be the ?on? position.
  12. 60A is it's rating, it will not trip as it's just a switch.
  13. Agreed that 14 AWG & a 25A circuit breaker is code compliant, & if a 25A breaker could not be found, a fusible pullout A/C disco is cheap & then 25A fuses could be installed...... "Wire it to the minimum, overcurrent protection to the max." That is how bids are won.
  14. It is a molded case switch, MCS, it provides no overcurrent protection. Edit: Since it is a FPE, if it was a circuit breaker who knows if it would work.[] They were common around here for a while for A/C disconnects.(The FPE MCS's).
