The wire sizes given are suitable for a 15' (4.6 meter) “round trip” length. In certain installations

the wire lengths to certain component parts may exceed this. If this is the case in your

installation find the maximum current draw from the list below and use the wire sizing table

shown on the next page to identify the correct wire size. The Micro HPS draws 28 amps at 12 V

while the refrigerator or freezer is running, and 45 amps at 12 V while the air conditioning is

running. Remember, the wire length is always considered to be the total distance from the

power source to the device and back again. The table below gives the current draws which

should be considered when sizing the wire runs. The DC is rated at 12 volts and the AC at 110

volts. Multiply by .5 for 24v and 220v.

● Micro HPS (DC) - 50 amps ● Solenoid Coil (ea) - 2 amps

● Water Pump (DC) - 10 amps

● Arctic Air Fan (ea) - 2 amps

Basic Electrical Wiring

Closely follow the wiring schematic and written identifications of the wiring connections which are

included in the sleeve of this manual. In planning your wiring remember:

1. Use only 100% tinned stranded copper wire of the recommended AWG size.

2. Always use the recommended size circuit breaker on the main power line.

3. Butt splices should be crimped and sealed with heat shrink tubing.

4. When making connections to the terminal block, be sure to tighten the clamping screws firmly.

(All high-power connections should also be rechecked for tightness at regular intervals)

Wire Size

In addition to using the right type of wire, it is also important to use the correct wire size. While

this is important for both AC and DC systems, it is in high-current DC systems that installers tend

to underestimate the size of wire needed. Refer to the tables on the following pages for a

general reference when selecting a wire size as a function of length and current. The Glacier

Bay wiring diagram calls out wire size by AWG gages. AWG is used in the United States while

Metric diameter is used in the rest of the world. For convenience, an AWG - Metric conversion

table is also provided.
