Car cable for ambulance (which plug is valid A or B?)

francisco

Starting to get Involved
Hi,

I have a doubt, I have to power another medical device (it doesn't have applied parts, it will also be class II) inside ambulance.
I have two type of power supply cable (A and B). From the point of view of electrical safety...which of them is better to the operator? Both are the same or one of them is better?. You can see these options in attachment file.

Remember 60601-1 (subclause 3.120) "An external d.c. power source (e.g. in an ambulance) is considered as a SUPPLY MAINS" .
Does this subclause entire say that option "B" is better and mandatory?
(remember that the negative pole is accessible on the plug in option "A" however in option "B" isn't the case)

This model plug (Option "A").....is valid to an medical power adapter (attachment file) but isn't correct to connect directly in ambulance?

Thanks
