Buying Guide

Match gauge to amp draw

Choose thicker wire (lower AWG) for higher current loads to reduce voltage drop and heat in indoor wiring runs

Prefer correct conductor type

Copper-clad aluminum (CCA) is common and lightweight; full copper offers better conductivity but costs more

Check wire length and color coding

Select lengths and multiple colors to reach runs and keep power, ground, and lighting circuits clearly separated

Inspect insulation and flex

Look for durable PVC insulation and flexible strands for routing through tight indoor spaces without kinking

Plan for grounding quality

Use dedicated ground runs with adequate gauge and secure terminations to minimize noise and ensure safe operation
