Pure LED Parallel Wiring
These examples have been formulated for the Hunza Wall Mount Transformer, which offers 3 output taps: 12v, 13v and 14v. Calculations were carried out using the Hunza Cable Calculator, which is available from your local HUNZA representative.
Example 1. Single Cable Run
19 mtrs (62ft) x 6mm sq (10AWG) cable supplied at 14 volts. Fixtures must not be connected closer than 12 mtrs (39ft.) from the transformer to prevent over-volting. (see right hand side of read out window next to Min. distance to first fixture @ 14v)
Example 2. Looped Single Cable Run
136 mtrs (444ft) x 10mm sq (8AWG) cable supplied at 14 volts from the transformer. Looping the cable back to the transformer allows the indicated distances on the calculator to be multiplied by 4. In this example the calculator indicated 34 mtrs (111ft) x 4 = 136mtrs (444 ft). This is the total length of the cable loop, so it effectively doubles the distance of the cable run from the transformer to the furthest fixture.
Example 3. Multi Cable Run
Supplied at 12 volts max. 6.5mtrs (21ft) x 2.5mm sq (14AWG) cable.
Supplied at 13 volts 14mtrs (45ft.) x 2.5mm sq (14AWG) cable. Fixtures must not be connected closer than 6.5mtrs (21ft) from the transformer to prevent over-volting.
Supplied at 14 volts 40mtrs (130ft) x 4mm sq (12AWG) cable. Fixtures must not be connected closer than 25mtrs (81ft) from the transformer to prevent over-volting.
Connect each of the three different cable lengths to the 12, 13, 14 volt outputs of the transformer to achieve the correct voltage for the cable length and load.
