I have a 5 Volt 20 Amp DC power supply. I was wondering if it is safe in terms of electricity shock due to high current output? Do I need to seal the connection to the device for protection?
Edit: Thanks for your answers.
Basically, I am going to connect the power supply to a string of LEDs which are all parallel (they have a series resistor to control the current of each branch). I want to know whether I need to seal the connection of the string and the power supply?
