How much power consumption / current does the PESD use of the line supply?

The short answer is very little. PESDs will use 400 micro amps of current to power the LEDs for the verification of the presence of voltage. The Multi Test Points will not draw any current until a multi meter is used to test for the absence of voltage. Upon testing, the current is still expected to be similarly minimum but is dependent on the meter that you choose to use.
