Can anybody determine, from that wiring, whether this is the LOAD or the LINE box in a three-way circuit? (I realize I could call a qualified electrician, so please don't suggest the obvious.) I was unaware there was a difference, but this switch, in Chinglish, seems to say that it can apparently only be installed in the LOAD side and that box is blocked by our dryer so it would be ineffective if installed there. Thanks for the help.
Disconnect the red wire & if it is not hot it is the load wire.
Please turnoff the breaker first and then turn it back on for the test.
