Can I wire two ballasts together and use one power cable Do both ballasts have to be earthed if they are connected?
Krystinkellylach
Yes, the two ballasts can be supplied with one power source. The two ballasts will be paralleled together. This means supply black (hot) to black on ballast one and black on ballast number two. Tie all three under a single wire nut. Connect the neutral conductors all together under one wire nut. Both ballasts should be tied to the ground wire that is in the supply cable. All of these connections must be made in an approved junction box.

How do you wire 3 - 4' fluorescent light fixtures end to end to 1 ballast?
More information is needed to answer this. We need the ballast and bulb type. If this ballast is not made to do what you want then it should not be done. It can cause damage to the ballast and cause fire.
Is the outer sheath on BX cable an adequate ground path?
It used to be, but now the ground wire (which replaced the aluminum strip) in the BX cable is used. The ground wire is now used to complete the grounding of connected devices rather that the sheath of the BX.
Can ammeter be connected in neutral wire?
No, your live (brown) cable takes the load and pulls the amps from the supply, not the neutral. Your ammeter should be clipped on the live to get a correct reading.
What is the cable size for a 26kw induction motor 50metre run for cable 415v?
Wire sizing is determined by the amount of amperage that the connected device draws. Look on the nameplate of the motor and state the amperage. Then the question can be answered.
What is the Phase to phase voltage of 66KV earthed cable?
Nominal transmission and distribution voltages are line voltages. So '66 kV' is a line-to-line voltage. Note that there is no such thing as a 'phase-to-phase' voltage -the correct term is 'line-to-line'. Using the term, 'phase-to-phase', indicates a lack of understanding of a.c., which is not uncommon! Incidentally, the symbol is 'kV', not 'KV'.
Difference between earthed and unearthed cable?
For earthed and un earthed XLPE cables, the IS 7098 part2 1985 does not give any difference in specification. The insulation level for cable for unearthed system has to be more. In simple statement the manufacturers states that 11 KV earthed cable is suitable for use in 6.6 KV unearthed system.The process of manufacture of cable is same. The size of cable will depend on current rating and voltage level.
Where you have select unearthed cable?
Earthed cables shall be used wherever the syem Neutral grounding Solidly. Vise versa-Un earthed cable shall be used wherever the syem Neutral grounding through NER or Reactance.
Why cables are earthed?
The cable sheathing is earthed as a protection method in case of single-line-to-ground, double line-to-ground or three phase faults. This prevents damage to plant and personnel.
What would happen if you connected 2 laptops together?
you can network two laptops if you use a crossover network cable.
How can two switches be connected?
Traditionally, two switches can be connected together with a crossover cable. A crossover cable should be used whenever two of the same network devices need to be connected together. e.g. Connecting a router to another router, a switch to another switch or a PC to another PC. Using a crossover cable is not always necessary however. Most new network devices include a feature named Auto-MDIX (Medium Dependant Interface Crossover). Auto-MDIX detects what type of cable is connected and automatically changes its own configuration to enable data transmission to the other device. i.e. It does not matter if you use a straight through cable or crossover cable on Auto-MDIX enabled devices. Both will work.
Are power cable armour to be earthed at both ends or at one end only?
One end only. Single point grounding is a rule of thumb. The reason for this is when you run cables together, including a shield or ground cable, the cables with power flowing in them will induce a voltage on the other cables. If two grounds are placed on a shield or ground cable, unwanted current will flow in a loop through the cable.
What is peer to peer lan?

Is the negative battery cable considered as the ground?
The battery cable that is grounded, is connected to the body of the vehicle. Sometimes it is the negative cable & sometimes it is the positive. You need to check which cable is connected to the body of the vehicle.
Which cable is positive and which is neg?
On a vehicle the red is positive (+) and the black is negative (-). If they are not color coded the cable connected to the starter is positive and the cable connected to the engine or chassis is negative.
What happens when you plugin the Ethernet cable to your PC?
