What does a multi terminal block (MTB-01) do?
It simplifies the wiring of multiple low voltage fixtures to a transformer. Instead of having a blob of wires to a wire-nut, it can be made much neater and allows better connections with an MTB-01. The MTB-01 can accommodate up to 6 fixtures only. The output (12V) wires connect to the input terminal of the MTB-01, marked “A”. Meanwhile, the wires from the 6 fixtures connect to the 6 output terminals of the MTB-01, marked “B” through “G”. Refer to installation instructions for wiring details. 26.
