Type B 22 AWG Hook Up Wire M16878/1
More often than not UL, or Underwriters Laboratories, is the company that tests and approves wire and cable to make sure that it complies with the standards it presents.
However, in the case of Type B hook up wire the military is the organization approving its functionality.
The "M" at the beginning of M16878/1 designates that it's a "Mil Spec" cable or a military specification approved wire.
22 AWG wires come with many different types of insulation starting with the most basic called PVC or Polyvinyl Chloride.
It's the cheapest version of hook up wire unless you need a grounding wire without insulation at all.
Usually ground wires come in a solid strand of copper but it's also offered in a stranded version for additional flexibility.
PVC 22 AWG wire is commonly used in electronics and appliances throughout your home or even a commercial building.
Engineers design the wire and insulation, manufacturers make it, suppliers distribute it to assembly houses in which it's cut down and assembled into a wire harness.
You might have seen a wire harness if you've ever pulled a stereo out of your car or pulled the side panel off of a computer PC.
It has a plastic housing with many wires attached to one end that each has a function in terms of connecting power from one source to another.
The insulation of Type B M16878/1 is rated for 600 volts and has a temperature rating of 105ºC.
Again, the military has tested and approved this type of insulation to do just that and printed it on the wire itself.
For a PVC wire with higher voltage you can use Type C (1000 Volts) or Type D (3000 Volts) which both have the same temperature rating.
If you need a high temperature hook up wire you can use something called PTFE wire which uses a compound of elements to resist and withstand high temperatures.
If you're building a wire harness that will need to be put through an oven PTFE wire can withstand the high temperatures while PVC insulation would melt exposing the copper.
Jumping from PVC to PTFE will increase the temperature rating to 200ºC but it will also cost quite a bit more money due to the silver-plated copper strands and the more expensive insulation.
Speak to your supplier about the application you have to find out if you need PVC or PTFE insulation.
Hopefully you can get away with PVC so that you can save money but make sure you get the correct wire for your needs or it will come back to haunt you later.
