The National Electric Code requires min. 3'0" there are several rules defined in section 110.26 of the NEC; for 600 volts or less it is: * left to right the minimum clearance is 30" or the width of the equipment, whichever is larger * in height, there should be 6' 6'' minimum height to stand in front of the equipment (exception for dwelling units for panels 200 amps or less) * the depth in front of the equipment varies depending on the voltage and surfaces of the opposite wall behind you: if the voltage is 150 volts to ground or less the depth of clearance is 30": as stated above; if the voltage is higher it depends of whether the opposite wall is insulated or not: if insulated the depth is 3' 6", if not insulated (such as cement block) the depth is 48"
I refer to these rules as the "refrigerator rule": the clearance in front of the equipment in question requires a dedicated clear space roughly the size of a large refrigerator

Yes, it is 36" clearance in front of the box and 30" clearance on either side of a service panel or disconnect.
No, there has to be a three foot clearance in front of the panel. This is so that electricians can work safely on the panel.
The door cannot open and interfere with the panel. There must be 36" of clearance in front to the panel and 30" to each side.
Answer for USA, Canada and countries running a 60 Hertz supply service.The clearance in front of a distribution panel is 3 feet or 1 meter depending in which country you live. Around the distribution panel there is no distance stated. An in wall flush distribution panel has zero clearance.
yes wires is electrical panel
