circuits that have overcurrent protection as defined by Article 240 of the U.S. NEC.
Product power inputs with a current ratings of 16A or less must have a branch
■
circuit, or a supplementary overcurrent protection device, rated at no more than
20A.
Product power inputs with current ratings of more than 16A must have a branch
■
circuit, or a supplementary overcurrent protection device, rated at no more than
160% of the product input current rating.
Other national or local electrical codes might apply to the installation of this
■
product.
As a general guideline, overcurrent protection devices should be rated at a minimum
of 125% of the product input current rating in order to provide reliable power under
high temperature and transient voltage disturbance conditions. However, you must
consider the characteristics of the protection device and the applicable electrical
codes when selecting the rating of a protection device for the product installation.
Note – Overcurrent protection devices must meet applicable national and local
electrical safety codes, and be approved for the intended application.
