Hi,
just looking to see if anyone can recommend a supplier for 6000-1' jumpers with a male and female MC4 connectors already installed.
thanks

As soon as I saw the OP I immediately knew you'd be replying!
Is it really too late to switch the module stringing from landscape to portrait?
the system is already installed and online. it looks a lot worse from looking straight up at the wire instead of this side shot
Who pays for a change out like that? Surely it is possibly poor workmanship, but how can that be enforceable other than just threatening reputation?
To me is a code violation as the wires are bent tighter than what the code allows but that is never enforced.
300.34 Conductor Bending Radius The conductor shall not be bent to a radius less than 8 times the overall diameter for nonshielded conductors or 12 times the overall diameter for shielded or lead-covered conductors during or after installation. For multiconductor or multiplexed single-conductor cables having individually shielded conductors, the minimum bending radius is 12 times the diameter of the individually shielded conductors or 7 times the overall diameter, whichever is greater.
Section 300.34 covers the general rules for conductor bending radius:
Wouldn't Art. 300.34 only apply if the system voltage was over 600V?
... I was under the impression that for PV wire and USE-2 installation methods [in systems under 600V] we should reference Art. 338 Service-Entrance Cable, and Art 334 Nonmetallic-Sheathed Cable. Art. 338.24 Bending Radius reads, "...shall not be less than five times the diameter."
Is that incorrect?
Where not covered specifically in Code, the default is per manufacturer's instructions, if any.... There would be no actual code restriction on bending listed PV wire in my opinion. ...
Wouldn't Art. 300.34 only apply if the system voltage was over 600V?
338 does not apply to PV wire. There would be no actual code restriction on bending listed PV wire in my opinion.
Article 334 does not apply, no way no how whatsoever.
If 334 does not apply "no way no how whatsoever" where do we look for requirements on securing and supporting? Art. 338.10(B)(4)(b) is what I have been using which says, "shall be supported in accordance with 334.30." Should we be looking elsewhere for guidance?
Granted the wiring appears to be supported in the OP's photo, but that can definitely be another issue with short leads, and may be a problem elsewhere in this system.
