[RE-wrenches] transformerless inverters and conductor colors

[Marco Mangelsdorf]

Hi all,

 

We're doing more and more installs with TL inverters (SMA and P1).

 

I'm using double-insulated wire from the array string to the first
enclosure, as in j-box, and then transitioning to standard THHN/THWN wire.

 

I recently purchased some of that #10 double-insulated wire, getting a spool
of black and white.

 

Then after receiving the two spools it occurred to me: since the array is
ungrounded, as far as there being no grounded conductor in the circuit, did
I blow it by getting a spool of white wire?

 

What sayeth you all?  Can I not use that white wire in those array circuits
for TL inverters?

 

Thanks,

marco
