just loop the wires and leave them suspended and if they are over the rail
even better you will never see them

 Except if it is UL listed and tested as part of the assembly. Haha. I
 seriously don't that happened, but technically...

 Bottom line, a manufacturer should supply guidance on this.

[RE-wrenches] Enphase production CT with Sunpower PVS5

[Dave Tedeyan via RE-wrenches]

Hi All,
I am expanding on an existing Sunpower system, with non Sunpower equipment
(SMA inverters). In order to get their consumption monitoring to work
properly, I would like to install a production CT for the PVS5. Does anyone
know whether you can use an Enphase production CT with a Sunpower PVS5? The
Enphase CT is rated at 0.5V at 200A (at least that is what it says on the
CT label). I would prefer to just get a Sunpower production CT, but I am
not sure that I can being that we are no longer a Sunpower dealer.
Cheers,
Dave

Re: [RE-wrenches] Enphase production CT with Sunpower PVS5

[Nick Soleil via RE-wrenches]

Hi Dave,

I don’t know the specifications of the PVS6 production CT, but it is highly 
unlikely that it is a mA CT with 2000:1 winding ratio like the Enphase 
production CT.  You should try to source a Sunpower CT.
