Frequently Asked Questions
Q: What is a Class 2/Class 3 Circuit?
The National Electrical Code (NEC) defines a Class 2/Class 3 circuit as the portion of the wiring system between the load side of a Class 2/Class 3 power source and the connected equipment. This wire meets the requirements for being able to be used in a Class 2/Class 3 system.
Q: Don’t Class 2 and Class 3 wires need to have the CL2 or CL3 rating to be used as part of a Class 2/Class 3 system?
You would be correct in thinking that! However, Table 725.154(A) of the NEC says that you are allowed to substitute specific wires in for other wires that are designated CL2/CL3. This same table describes how a wire with a plenum rating can be used in both riser and wall applications, which includes this CMP wire.
Q: Is there an easy way to calculate possible voltage drop?
There are some online tools that can help you calculate voltage drop. We use calculator.net Voltage Drop Calculator. You simply input the data regarding your run (voltage, run length, amperage, preferred wire gauge etc.) and the calculator will let you know the voltage drop percentage. However, we recommend consulting a certified electrician in order to get an accurate recommendation.
q: Where can I find a gauge of wire you don’t carry?
Low voltage stranded wire can be found in a variety of gauges at local hardware stores and major home improvement stores.
