Can someone tell me what type of connector this engineer is asking for? Job is an Albertsons Express
"All joints in conductors shall be made by first twisting the conductors and then apply a UL approved insulated, cadmium plated, live steel, spring type connector in all sizes up to the catalogue capacity of the connectors. Wire nuts will NOT be accepted."
In my experience most job specs are an error filled joke, 90% being boiler plate stuff that gets cycled from job to job. Apparently if the spec book weights more than 3 lbs. the engineer can justify a higher fee.
My current job the spec. for sleeving conduits through masonry walls is obviously copied directly from a plumbing spec. complete with the requirement for chrome escutcheons. Have you ever installed chrome escutcheons on your electrical conduit? Well my spec says that I have to!
e57, Those look like like Wago connectors. But if you "Pre-twist" the wires, how do you insert them? Perhaps you should send an e-mail to the President of the Engineering company requesting the name and school that this "engineer" graduated from. Explain that you need the name of the school so you can send a letter to the Dean of the school asking if it is possible to revoke the diploma of this so-called graduate. ~Peter
