How Many Amps Before You Need a Relay?

There are two main types of relays: electro-mechanical and mechanical. Electro-mechanical is the most common, and is used in low voltage automobile applications. It functions by activating an electric field. The latter type of relay is often the most expensive. Nevertheless, they are very common in vehicle electrical systems. The main difference between the two is their operating voltages. An electro-mechanical relay can handle up to 20 amps and is generally less expensive than a mechanical or electronic relay.

How many amps before you need a relay

In automotive applications, the typical automotive relay will handle at least 30A, while a fuse holder can only handle ten or twenty amps. However, if you are running a rock light circuit on a truck, you may need to install a relay instead of a fuse. While 22 gauge wire is fine for individual lights, you may want to use 16 gauge wire for the feed line.

Relays are usually rated for AC or DC voltage. This shows the maximum amount of power they can switch, but it doesn’t necessarily indicate how much power they can handle. A 5 Amp relay rated at 125VAC will be able to switch five Amps at 250VAC, while a 10 Amp relay at 24VDC can handle thirty-five Amps.

LED Light Bar Relays

A relay is a device that controls electrical currents in a circuit. These devices can be used for LED light bars, high-beam headlights, or reverse lights. These components are typically pre-wired and come with a switch and wiring harness. Relays are typically used to protect low-powered circuits from damage. The main reason why a LED light bar requires a relay is because it has a high-power draw.

Why is a relay needed for LED light bar

A relay is required to operate an LED light bar, since the bulbs themselves have a separate circuit. Relays are needed to control the lights, as the LEDs have their own circuits. A power source needs to be connected to a relay to avoid damaging them. An LED light bar can be damaged by high current values, so it’s important to use a relay. Also, it can be dangerous to install LED lights in unprotected areas.

A relay is required when wiring an LED light bar, because a light pod with a low amp draw doesn’t need a relay. But a large LED light bar requires a relay switch. While a light bar without a relay switch is not illegal, it’s best to use a professional mechanic to complete the installation. In general, LED lights have a long lifespan, and a relay is essential for their longevity.
