How To Prevent Voltage Drop4 Key Tips for Low Voltage Lighting Systems

www.pegasuslighting.com

As an electrical current travels farther and farther and farther down the cable it can grow weaker, causing the bulb on the end that's farthest away to appear dimmer than the bulbs that are closest to the transformer. This event is referred to as voltage drop.

What Is Voltage Drop?

Fortunately there are several tips that can help you avoid the dimming from voltage drop. Remember these four things:

Can I Prevent Voltage Drop?

Short Thick Twist Split

Keep the distance between the transformer and the lamp(s) as short as possible. The shorter the distance, the

less the voltage drop you will experience.

Tip #1: Short Distance

Use thick (low gauge) wires on the secondary/output side. The thicker the wire, the less the voltage drop you will

experience.

Tip #2: Thick Wires

Try to use a pair of secondary wires that are twisted together in your electronic transformer. The closer the two output wires are to each other, the lower the voltage drop

you will experience.

Tip #3: Twist the Wires

When a low voltage transformer powers more than one fixture or circuit, split the output immediately into several separate circuits rather than carrying all the power in one

pair of wires. The less power per circuit, the less the voltage drop you will experience in your electronic transformers.

Tip #4: Split the Output
