William,

Why not use the nifty Combi-Switch which has four Littelfuse high voltage
fuse holders integrated into a CTL listed HU361RB disco and enclosure?

Friends:

Now that it is more common to use higher rated battery-less grid-tie
inverters, string fusing is now more of an issue.  For example, the SB6000
will require string fusing with a typical three string installation.

I would like to use a combiner for this series fusing as well as for
disconnecting means.  This means a combiner will need 600 V rating on all
parts, rating for disconnection under load and a dead front.  Anyone know of
such a product?
