Can I use a Type 3R rated SolaDeck enclosure to combine
PV strings?
The Type 3R SolaDeck enclosure is not listed or labeled to meet the standard for combining PV strings. There
are SolaDeck models that are rated, listed, and labeled to the UL1741 standard for combining.

How is a SolaDeck Type 3R enclosure typically used?
The Type 3R rated SolaDeck models are listed for outdoor use and typically are being used for simple pass through of the wire or a junction box for transition of wire.

What is best way to transition the PV wire with a SolaDeck?
Wire nuts can be used but rail mounted terminal blocks are rapidly becoming the method of choice. Terminal blocks are
non-fused connection devices that provide a visibly clean installation for easy labeling. We offer varying models of terminal blocks to work in conjunction with your SolaDeck model.

Does the installation of a SolaDeck require any special tools?
Over and above the tools listed in the installation manual, a knock out tool is essential to make the holes for either strain fittings or conduit entry above the roof deck. Every SolaDeck model has preconfigured dimple locations used for centering these entry holes.

How many pairs of conductors can be installed in a SolaDeck? The number of conductors that can be installed in a SolaDeck is limited only by the conduit and fittings used to enter the enclosure above the roof deck. At this time six pair (twelve conductors) is the maximum. Modifications are in process to increase the number of conductors.

Can I use breakers in the current SolaDeck models? Our current SolaDeck models can't accommodate breakers simply because the breakers are too tall for the enclosures. RSTC is working to design new models that will address the use of breakers for both AC and DC current.
