I have two simple questions: 1) I have equipment which will be tested according to IEC 1010-1. This particular piece of equipment requires a mains 10 amp fuse at 230V line. I looked at some fuse manufacturers and they have fuses rated for what I need, but aren't necessarily IEC approved or are not approved for certain countries (like Denmark only accepts up to 8 amps when using IEC 127 fuses). Are there any fuses which are approved for all countries which can handle the current requirements? I would prefer using the standard 5 mm X 20 mm size fuse.
2) This same piece of equipment will produce an accessible hazard in-order to fulfill it's proper function (20 kV and 30 mA). IEC 1010-1 states that I need an emergency switch. Does this switch have to shut down all the power to the equipment (break the mains), or can I use it to break power just to the Hazard generating circuitry? This would allow me to allow the cooling fans and some low voltage ( less than 15 volts peak) circuitry to remain active. Or, can I use it to activate an opto-coupler and/or a solenoid device which would break the power for the unit? Any help would be appreciated. Thanks in advance.
