Similar to other product rating systems, like UL, an IP rating is an international standard that sets guidelines for electrical devices. An IP rating reviews a product’s ability to protect itself against water and solid substances like dust, dirt, etc. Consider an IP rating like a score that measures how waterproof or dustproof a certain product is.
For example, a light bulb could have an IP rating of 54, which would suggest that it offers a moderate degree of protection from dust particles and liquid. However, a light bulb with an IP rating of 68 would indicate that it’s completely dustproof and waterproof.
IP stands for Ingress Protection
Each IP rating has two numbers. The first number refers to the degree of protection from solid particles, and the second number is the degree of protection against liquids. Use the chart below to help you understand IP ratings better!
Hopefully now you can begin to understand what IP ratings really mean, but you might ask yourself, “How do I know which IP rating is the best choice?” Well, there is a general rule of thumb when choosing the right IP rating. If your electrical device will generally be used indoors, then a low IP rating is appropriate. However, devices meant to be used in outdoor locations should have a higher IP rating, because they are more susceptible to rain or dust.
For example, if you’re looking to purchase light bulbs for pool or shower areas, lights that are rated IP65 are most suitable. However, an electrical outlet with a rating of IP22 should only be used indoors, where it is least likely to come in contact with liquid or dust particles.
Making an informed decision just got easier. Make sure you’re choosing the right ratings required by your state’s code and regulations.
The National Electrical Code has made some changes that may affect any installations made after September, 1 2017. As of July 1, 2017 twenty states have adopted the 2017 NEC code regulations, and more states are in the process of adopting and implementing the 2017 NEC.
RoHS identifies hazardous substances that can pollute landfills and harm people. WEEE works alongside RoHS to ensure that your products meet the standards.
Weather ratings, like damp location, wet location, and dry location, inform you where you can use a bulb. Discover the difference between damp and wet locations as well as what a dry location rating indicates.
