How does one wire a transformer?
The transformer should be connected to the wires leading to the lighting fixture using wire nuts or terminal blocks of appropriate size (for solid contact). Please check carefully that input wires are connected to the power line and output wires to the lamp. Low-voltage halogen systems carry relatively large currents so all connections must be very tight to prevent a fire hazard. If transformer is equipped with wires, then you will usually find the thicker wires on the low voltage side and not vice versa.
