Spade Terminals

FAQs

Should I choose tin-plated copper connections for connecting two wires?

Yes, choosing tin-plated copper connections for connecting two wires is a good option because they offer excellent conductivity, corrosion resistance, and durability.

Does a variety of spade terminals help in saving space in a junction box?

Yes, a variety of spade terminals can help save space in a junction box by allowing for organized and efficient connections, ensuring that wires are neatly arranged and easily accessible.

Industrial Wiring Tips and Tricks

Wire Type

MTW is typically used in industrial control panels. The flexibility of the wire allows it to be easily maneuvered through wire ducting. THHN wire is commonly found in homes or commercial buildings. The rigidity of the wire makes it easier to pull through conduit. XHHW wire is similar to THHN but provides a more protective insulation.

Wire Color

The National Electrical Code (NEC) or UL are great points of reference when trying to decide what colors of wire to use. For example, UL standard states that a ground wire should always be green, an AC hot or live wire should be black and AC neutral should be white. These are just a few examples of UL code requirements.

Wire Size

A simple rule of thumb when selecting wire size is, the higher the current, the larger the wire. It is also important to consider the bend radius of the wire. If a wire is bent too sharply, the conductors within the insulation can be damaged.

Wire Connection

It is important to make sure that the wire is connected properly and that enough torque has been applied. If enough torque is not applied to the electrical connection, the wire can become loose over time resulting in a poor electrical connection. Too much torque can damage the the wire and electrical equipment.

Wire Labels

Labeling is essential when performing any kind of electrical wiring. Proper labeling will allow others to easily identify the function of a wire, where it is going and where it has been. It can also make troubleshooting on a panel or any electrical device much easier when worked on at a later date.
