What is the difference between reverse current and overcurrent protection?
A reverse current relay senses Power in (uses both voltage and current, and looks at the phase angle between these), and operates if power is flowing in the reverse direction, and the current is above a set point. An overcurrent relay looks at only current, and operates if it is above a set point regardless of power flow direction. Reverse current relays are often referred to as reverse power relays.
What is the difference between rewire-able fuse and catridge fuse?
the rewireable can be dissembled and has some sort of chucks to hold a new element
Differetiate between solid earthing and ELCB?
ELCB is the connection to the direct earth path using protective device.while solid earthing is without protective device.A form of ELCB should be installed when direct earth path of low enough impendance can not be obtained.
What are electrical fuses?
Safety devices used in electrical circuits.AnswerA fuse is an overcurrent protection device, and will operate in the event of a sustained overload current or a short-circuit current.
Where is Volvo 850 horn relay?
towards the front left end of the fuse box it should be fuse number 12.
Why would your lights and horn not shut off?
Have you checked for a relay that might have been damaged when the fuse blew? With an overcurrent, it is possible for the relay to pick up and then become 'welded' so it will not release. If you find the relay and remove the cover, the contacter should move when you apply a little pressure to it. If this doesn't happen, replace the relay. Much harder to check would be if insulation melted during the overcurrent and fused power to a horn and light wire. Relay for sure.
Will a relay with a 40 amp rating function properly in a circuit with a 30 amp fuse?
Yes, a relay with a 40 amp rating can be used in a circuit with a 30 amp fuse. The fuse is designed to protect the circuit from overcurrent, while the relay's rating indicates the maximum load it can handle. As long as the total current drawn by the circuit does not exceed the fuse rating, the relay should function properly.
What is the difference between fuse and MCB?
what is the difference between miniature circuit breaker and fuse
Why does ecm 1 fuse blow?
There is an overcurrent/short in the circuit.
The fuse between 12V car battery and relay for 2x 100w spotlights keeps blowing?
obviously you need a bigger fuse and a bigger relay
What does OPD mean in electric terms?
'Overcurrent protection devices' are used to protect conductors from excessive current flow... a fuse
What is the difference between reverse current and overcurrent protection?
A reverse current relay senses Power in (uses both voltage and current, and looks at the phase angle between these), and operates if power is flowing in the reverse direction, and the current is above a set point. An overcurrent relay looks at only current, and operates if it is above a set point regardless of power flow direction. Reverse current relays are often referred to as reverse power relays.
Fuel relay fuse?
can a fuel relay fuse make car not start? If the fuse or the relay is bad, yes.
A fuse has low melting point why?
This is necessary because a fuse is a protection against an overcurrent; excessive current produce melting.
Where is the ac fuse between the fuse box and ac relay on a 77 Chevrolet Malibu Classic under dash or the hood?
There is a fuse for the air conditioner and one for the fan. You have a power source to the fuse. From the fuse the relay gets it's power and then the fan and or the air conditioner compressor.
Is there a fuse between the fuse panel and the fuel pump on a 1998 Isuzu Hombre 4-cylinder?
There should be a relay location(?)
Fuse keeps blowing when replaced?
There is an overcurrent situation in the circuit, could be a wire shorted to ground.
