Safe limits of amperage
WebThe USB Battery Charging Specification allows devices to draw current in excess of the default power limits. The first version of the specification (BC 1.0) was released in 2007, followed by version 1.1 in 2009, and the current, BC 1.2, in 2010. BC 1.2 introduced three types of downstream ports: WebElectrical safety basics. Don't work with exposed conductors carrying 50 volts or more. Make sure electrical equipment is properly connected, grounded and in good working order. Extension cords may not be used as permanent wiring and should be removed after temporary use for an activity or event. Surge suppressors with built-in circuit breakers ...
