ReadyWatt Medium & Large Pass-Thru Boxes

These ETL® listed ReadyWatt® Pass-Thru Wiring Box are intended to provided a robust, secure, and code compliant method of transferring the MultiContact USE-2 type conductor coming from the PV array to THHN/THWN-2 type conductor. The PTWB also provides a convenient location to begin the necessary conduit run from the PV array to the power conditioning equipment.

In the Large Pass-Thru Box, the terminal blocks are not paralleled, therefore each string remains independent of the others.

The Medium Pass-Thru Box also serves as a junction box in that it parallels the two PV strings into a single output to the inverter.ReadyWatt® Pass-Thru Boxes are Rugged, Code Compliant, and ETL® Listed
