Which type of capacitor has the highest voltage rating?
Those with vacuum as the dielectric have.
How do you know the voltage of your outlet?
This is a hard question to answer, since there is no visual signs on the outlet themselves, but if you can find any type of appliance, the voltage rating _should_ be on that.
Does a high rating mean lots of insulation or little insulation?
It depends what you mean by a 'high rating'!If you mean a high 'voltage rating' then, yes, you will require thicker insulation. But if you mean a high 'power rating', then, not necessarily, because the voltage can be low, while the current is high.Remember, the thickness of insulation depends on the voltage, while the type of insulation (how it withstands higher temperatures) depends on the current.
How long for a cable to heat up at maximum current rating?
It depends on the surround material, temperature, type of cable, and what you mean by "maximum current rating". Typically a maximum load current rating will be specified, such as 15A; this means you can push 15A through that cable nonstop without damaging it (it won't overheat). You might have a short time rating as well, such as a 4 hour rating, where the cable can handle runing 22A for 4 hours if the surrounding temperature is kept to some value, though this may slightly degrade the insulation. There's also a fusing current rating for many cables. At this current, the cable will eventually melt (like a fuse).
Which type of diode used in bridge rectifier?
depends on current/voltage rating. schottky are preferred since they have a lower activation voltage, they are fast and their reverse recovery is small. otherwise you can go to freds, if your reverse voltage is high enough to forbid you schottkys.
What is the ampacity of 25mm cable?
the load rating for this type of cable is 100amps.
Can you plug a dc cable into a wall outlet?
With the proper cap configuration on the DC cable, yes it physically can be done. If there is a DC load connected to the end of the DC cable, the load would be destroyed by the application of AC voltage being applied to it. Why anyone would consider doing this type of procedure is anyone's guess.
Which type of capacitor has the highest voltage rating?
Those with vacuum as the dielectric have.
What is cable schedule?
Cable schedules provided a tabulated list of all cables with relevant details such as cable number, cable type, size and rating, voltage, number of cores and length of route. Cable schedules are applicable for power cables, control cables, instrumentation cables and industrial data communication cables. In addition to the cable schedules, termination diagrams are provided for use by the electrical installation contractor.
How can you select cable gland for a 240 sqmm cable?
It depends to Overall Diameter, type of armor, Lead Cover and voltage grade.
What size cable for 37.5 kw 3phase motor?
Incomplete data: To have an accurate result - please provide the following; 1. Voltage Rating - Low Votage or Medium Voltage Applications? 2. Efficiency 3. Power Factor 4. Distance - One way distance from source 5. Location and method and arrangement of Installation 6. Allowable or acceptable voltage drop 7. Type of cable - PVC or XLPE cable with same size has different ampacity

Is stacking of cables in cable tray permitted?
See NEC Article 392. It depends on the voltage, conductor size and the type of cable tray selected.

What is the voltage rating of the conductors in type nmc cable?
In North America the voltage ratings of low voltage wire comes in three voltages. The voltages are 300, 600 and 1000 volt insulation ratings.
In an emergency a low voltage cable can be run up to 800 feet from the Secondary Distribution Center to what type of load?
resistive
