Is There a Distinction Between Class 2 and Class II Energy Provides?

Energy provides will be troublesome merchandise to buy from as a result of there are such a lot of completely different choices and many alternative laws you have to observe relying on the place your challenge is positioned. When you work in your challenge you would possibly come throughout sure laws which will require a Class 2 or a Class II energy provide. Now, these two classifications could sound comparable in dialog, however they imply two utterly various things. Nonetheless, each are essential classifications coping with the protection of the facility provide and the person. Class 2 refers back to the wiring necessities and energy capabilities, whereas Class II refers to an influence provide’s inside construct and insulation. 

NEC Class 2 Energy Provide

For an influence provide to be labeled as Class 2 it should meet the requirements laid out by the NEC (The Nationwide Electrical Code). These requirements cowl the wiring necessities and energy limitations of the facility provide as a way to scale back the danger of shock or hearth. Right here’s an outline of these necessities.


Class 2 energy provides should be constructed with In-Wall Rated wiring meant for everlasting set up, inside partitions or flooring, the place they might be surrounded by insulation. These wiring necessities assist forestall cracking or melting of the wire. With out these necessities, the facility provide can doubtlessly change into a harmful hearth hazard. 


The extra essential a part of the NEC Class 2 customary is the facility limitations of the facility provide. LED Energy provides can take 120V of energy and convert it down into low-voltage 12V or 24V energy. To ensure that the facility provide to be Class 2 compliant, 12V drivers should be 60W and underneath and 24V drivers should be 96W and underneath. These limitations are in place to decrease the danger of electrical shock or overheating from extreme currents. 

Nonetheless, for bigger tasks similar to residence remodels or industrial area builds, a considerable amount of energy is required to energy a number of lights. You possibly can set up a number of 12V 60W Class 2 LED Energy Provides or you may set up a excessive wattage multi-tap energy provide like a 12V 240W Class 2 LED Energy Provide. Excessive wattage multi-tap energy provides, like a 12V 240W energy provide, comprise four separate 60W outputs. Every output has its personal circuit breaker so if certainly one of them have been to expertise an influence surge the opposite outputs received’t be affected. Utilizing a big energy provide, when it’s wanted, is a extra reasonably priced resolution and simpler to put in than a number of energy provides.

Class 2 energy provides are sometimes recognized with the phrases “Class 2 Energy Provide” on the label of the facility provide. 

IEC Class II Energy Provide

For an influence provide to be thought of Class II, which is completely different from Class 2, it must observe the design laid out by the IEC (Worldwide Electrotechnical Fee). This code is important to guard the person from electrical shock. With Class II energy provides, there are two layers of insulation, or a single layer of bolstered insulation, between the person and the inner present carrying parts. In all these energy provides with two layers of insulation, the primary layer is also known as “Fundamental Insulation”. Fundamental insulation is the insulation that you just see across the wires popping out of the facility provide. The second layer is often an insulating case across the energy provide. Class II energy provides will be recognized on the label by a logo of a big sq. with a smaller sq. inside it. 

Class II energy provides are widespread merchandise that are available in direct contact with the general public. Some examples of Class II energy provides are your laptop computer or cellphone charger with a two-prong plug. Class II energy provides don’t require a floor connection (three prong plug) to guard in opposition to electrical shock. They don’t want the bottom connection as a result of the facility provide is grounded inside the product’s casing.
