Hello experts,

I'm trying to determine if any compliance requirements apply to Vdc electrical 
accessory ports included on a diesel engine powered hydraulic pump.   The 
machine provides hydraulic power to various specialized earth excavation tools, 
connected via umbilical hydraulic and electric lines.  For operator 
convenience, there are:

*12Vdc automotive style accessory socket
*dual USB style (power only, no data, no USB logo) port providing 5Vdc

The output voltages are labeled on the accessory panel, but rated and maximum 
output currents are not.  The USB-like port is limited by internal machine 
fusing, which is rated considerably higher than what a USB-certified port would 
provide.

Customer expecting to market primarily in North America and Europe.  What 
standards most directly apply to labeling or specifications of these accessory 
ports?


Thank you kindly,
Chet Summers
