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 the definition of a steel wired armoured cable in electrical engineering?
Underground cables are 'armoured' in order to protect them against mechanical damage. This armour takes either of two forms: (1) steel tape, or (2) wire. Wire armour tends to be used on cables with a larger diameter, as it makes them more flexible compared to cables with tape armour. In both cases, the armour is spiral-wound towards the outer part of the cable along its length and is, itself, protected with a hessian or plastic outer layer.
What are the methods of removing and replacing cables and wires in wiring enclosures without causing damage to existing cables?
It is tedious job. Each cable must be disconnected from power, disconnected from the terminals. A cable needs to be thus disconnected from both the ends, marked at both the ends, release the cable from the cable tray or from the conduit so that the cable is not damaged.
What is it called when a HFC cable powering system is designed to power one or more power inserters?
When a Hybrid Fiber Coaxial (HFC) cable powering system is designed to power one or more power inserters, it is referred to as a "Power Over Coax" (PoC) system. This setup allows for the simultaneous transmission of both data and power through the coaxial cable, enabling remote powering of devices like power inserters without the need for separate power lines.
What is the maximum voltage rating for AC-90 armoured cable?
The maximum voltage rating for AC-90 armored cable is typically 600 volts. This type of cable is designed for use in various applications, including building wiring and power distribution, and is suitable for both indoor and outdoor installations. It's important to ensure that the cable is used in accordance with local electrical codes and standards.
What type of clamps used for armor cable?
The most common ones are RG59 and a low loss cable is RG 6,both are 72 0hm for tv sets and antennas.

Why does a serial ATA drive sometimes have two power connectors on the drive?
One power connector is for the SATA power cable and the other is for the standard power cable. Use one or the other depending on what power connectors you have available in your system but not both.
Can I wire two ballasts together and use one power cable Do both ballasts have to be earthed if they are connected?
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.
Why is there no power to anything in a 91 Ford Escort LX?
Clean both ends of both cables and if that doesn't do it, check the cable ends.

How do you reduce induced voltage in control cables?
You can reduce induced voltage in control cable by applying the following methods. 1. While laying control cable keep a minimum distance 300mm from the power cable. 2. If possible try to lay control cable on the separate cable tray. 3. Earth the Armour/ screen of the control cable on both side of the cable or at-least at one side. Some times it is not important to reduce the the induced voltage in control cable, but it's effect on relay or contactor as the contactor or relay does not pick-down even after the removal of the control supply. In that case it is recommended to use two relay/contactor in parallel and use the contacts in series or parallel for control circuit interlocking.
What are cable cover used for?
Cable covers are used to protect cables from damage. They prevent the cables from water, falling objects, and dust. They are used for both communication and power cables.
Are monitor power cable and CPU power cable both same?
Just about every computer (cpu) uses a standard IBM power cord. Most monitors do as well, unless the power cord is permanently connected. Most computer equipment, other than printers and small devices, use the IBM power cord.
Hector stole achilles which Patroclus had borrowed?
Armor . He didn't steal it, taking a fallen foe's armour was recognised by both sides as a tophy the victor was entitled to.
What armour did cavaliers have?
The calviers and roundheads both had the same kind of armour. Most soldiers were given armour that covered their chests and backs. Armour was expensive and most of the time the infantry were given leather tunics instead. Although they couldn't stop gunfire, these tunics did provide some protection against swords.
Do routers work with both cable and DSL input?
Router can function using both a cable and a DSl connection
What cable do you need to hook your mixing board to your power amp?
You need to find out what output connections are on your soundboard and what input connections are on your amplifier. If you don't know this, a 1/4 inch cable usually will work at both ends.
