A510C Pro/Tran2 50-Amp 10-Circuit 2 Manual Transfer Switch

Switch arrived quickly,packaging was good,installation was a snap. Zero issues other than it did not come with wire nuts. But that's not a big deal,very solid product. Install took about 2 hours,mostly because I had to mount my inlet to brick that was a pain to drill though.pulling wire and hooking it up simple and clean.

Reccomended

It simply works as advertised! Very well made. relatively easy to install.

The transfer switch was easy to install. the feeding of wires through the flexible steel conduit was a bit of a challenge. Videos on the manufacture site were excellent.I wrote the manufacture when I connected my 6AWG wires to the red and black wires inside the transfer switch. The transfer switch uses 10AWG (red and black) for connection to your 6AWG wires for the 50Amp service to the switch. This counters my knowledge of using 6AWG copper wires for 50Amp circuits.The manufacture emailed me back and said NEC doesn't apply to wiring inside enclosures like the transfer switch. UL reviewed the switch and approved the wiring used for the 50AMP feed based upon temp rise of wires, the type of wires being used, and the fact it is inside an enclosure and not an inwall or conduit application. Here is what the manufacture said."I had the same question when I came to work at Reliance Controls in Tech Support. Here is the answer. Wire in a Panel is rated differently than typical Conduit wiring as rated by the NEC.The wire size that is typically associated with 50-amp is 6-gauge or 8-gauge when using 75° C wire, but the wire size does not apply to internal wiring inside of panels. Wire rating is arbitrary, once that is understood, everything should make more sense. The NEC wire ratings are specific to specific conditions.There are all sorts of wire ratings based on insulation temperature, type of insulation, and whether it's in a conduit or an open space cabinet/enclosure. It is not true that 10-gauge wires are 30 amps, and 8-gauge wires are 40-amps, and 6-gauge wires are 50-amps.The attached table 310.15 (B) (16) in the NEC shows this. Even so, this table does not apply to factory build control panels; it is just setting forth rules for wiring circuits in buildings through conduit. Nor does the table refer to 10-gauge MTW wire that is rated for 105° C which is used in the Transfer Switches.10-gauge wires can handle way more power than the NEC depicts in the table, as they want wiring in residential to be overrated. The wiring in our transfer switch is 10-AWG (105° C) MTW, but per the testing lab Underwriter's Laboratories (UL), none of these matters. They run very stringent heat rise tests with much higher amperages (for example, our 30-amp toggle switches must pass 60-amps for over 5,000 operations).The wire size in this transfer switch or other factory wired control panels that have testing lab certifications to a certain temperature rise unless there is a claim of a fraudulent marking for the certification. We have been passing 50-amps (plus) testing for nearly 20 years with 10-AWG 105° C wire, a lot has to do with the fact it's in an open enclosure versus in a conduit where the heat factor is much higher in a conduit. Now if you were running wire in a conduit between an inlet box and the transfer switch, that falls under applicable building codes, and different rules must apply (like using 8-AWG). But not in the transfer switch. "
