Hook Up Lead Wire AWM UL 3340-3374
Certain conditions call for highly specific types of wires. As such, the lead hook up wire was developed for highly volatile explosive working conditions with high temperatures. That could be motor engine or an electronics’ heat sink. This wire has an impressive heat aging attributes and doubles up as relatively low-cost systems lead wire for light motors. It is explosion proof so if you are contemplating a device or a machine that’s explosion proof, like a military device, this could be an excellent buy.
This lead wire conductor is an 8 AWG sized stranded piece enhanced with tinned copper. The set-up is put together in line with the specifications of ASTM B-33. 8 AWG is a considerably sizeable cable measuring 0.13 inches. Stranding is important because it makes the cable very flexible so that it can be folded for easy transportation and bent to fit into ducts during installation.
Lead wire AWM Hook Up cable complies with a number of good books like the CSA FT-2 specifications for fire compliance, UL 758 for 1250C/600V flexing cables, CSA CL for cables flexing at 1500C and CSA AWM 600 volts at 1250C.
The cable has a color-coded Ethylene Propylene. EPDM insulations are tough but highly flexible coatings for conductors. They don’t conduct current so you can handle the wire as it transmits power without worries over your safety. Moreover, it protects the underlying conductor from corrosion caused by moisture and industrial chemicals. It can’t be penetrated by UV light, water or oil and can absorb damaging impacts of physical impacts to keep the conductor safe. It’s easy to terminate, twist and fold without suffering wears and tears.
a) Motor lead wire
b) Electronics internal wiring
c) Military wire
Frequently Asked Questions - Hook Up Lead Wire AWM UL 3340-3374
Are there any special instructions I should adhere to when installing UL 3340 and 3374 wires?
Yes, there are instructions to follow when using these wires. First, you should not exceed the temperature rating given for the wires. These wires are rated for UL standard 150 degrees Celsius for non-flexing services. Usually, UL 3340 and UL 3374 wires come with specific temperature approvals and these ratings are based on whether UL standard is required for the application versus the CSA standard. UL standard for these wires is not rated for use in flexing services and this means that the wires can carry higher temperature ratings than the flexing CSA standard, which is rated at 125 degrees Celsius for the same wires. When it comes to voltage, ensure that you do not exceed 600 volts.
How do I identify UL 3340 and UL 3374 wires?
You can identify these wires by looking at the color of the conductor. The outer layer appears silvery white because it is made of tin. The conductor has a coating of tin material. On the inner part, it appears coppery due to the color of copper, which is the primary material of the wire. You may also want to look at the insulation, which is made of cross linked ethylene-propylene diene elastomer or EPDM.
What are the approvals for UL 3340 and UL 3374 wires?
These hook up wires have been approved for use in Class 155(F), 130(B), and some 180(H) systems. Both UL 3340 and 3374 have a temperature rating of 150 degrees for UL standards on non-flexing services. The CSA approval for the wires is CSA Type CL1254, which rates the wires for use in applications of up to 125 degrees Celsius for flexing services. The wires also meet flame compliances like CSA FT-2 and industry approvals like UL Standard 758 - Styles 3340/3374 and CSA AWM I A/B, CL 1503
In what applications can I use UL 3340 and UL 3374 wires?
These wires are used in heating and cooling appliances, motors, and generators as hook up wires.
Is there any special engineering in the manufacturing of these wires?
Yes, the chemically cross-linked ethylene-propylene diene elastomer offers combined features of silicone and Hypalon. This means that ethylene-propylene diene elastomer (EPDM) gives more resistance to abrasion than Hypalon.
