Terminal blocks increase safety by grounding, isolating, and protecting the other components in the electrical circuit. Terminal blocks are available with finger-safe connections to prevent electrical shock. And, terminal blocks can also provide test points, which add even more safety to the circuit. Are terminal blocks safe to use? Overheating and damage to a terminal […]

Due to unreasonable contact structure design, material selection error, mold instability, poor processing size, rough surface, unreasonable surface treatment process, such as heat treatment plating, improper assembly, poor storage and use environment, improper operation, etc., at the contact site. DO terminal blocks get hot? In the event of overload, conductive metal parts of the terminal […]

Terminal blocks at a glance Terminal blocks are connectors that terminate a single wire and connect it to a circuit or other system. Terminal blocks come in a range of shapes, sizes and ratings, but always terminate a single wire (single pole) and are never multi-pole. How many wires can you put in a terminal […]

What is a Relay and How Does it Work? A relay is an electrically operated switch. They commonly use an electromagnet (coil) to operate their internal mechanical switching mechanism (contacts). When a relay contact is open, this will switch power ON for a circuit when the coil is activated. How does a relay work simplified? […]

12.0 volts. Resting fully charged 12-volt batteries are around 12.8-12.9 volts, and flat dead ones are at 12.0 volts, so 12.4 volts on a resting battery means it’s about 50% charged. What voltage is too low for a 12-volt battery? 12.0 volts or below – At 12.0 volts your battery is considered to be fully […]

To find out precisely what the jumper pins do on your hard drive, just search “jumper pins” along with the model number and manufacturer of your drive. You’ll find the relevant support site that tells you which ones to use. Western Digital’s instructions for jumper pin settings on some SATA hard drives. How do you […]

When the voltage of the starting power supply is lower than 11.8V, it will be difficult to start the car. You can choose to turn off all other electrical appliances and try several times. When the battery voltage is lower than 10.8V, it is generally impossible to start the car. Is 11 volts too low […]

For most standard size cars, a set of cables rated for 400 amps will be sufficient. More powerful vehicles such as trucks and SUVs will need somewhere around 800-1000 amps in order to turn over the engine. Which is better 2 gauge or 4 gauge jumper cables? The lower the gauge (such as 1 or […]

Most of your current thermostat’s wires will be connected to your thermostat and go through the wall to connect to your HVAC system. However, some thermostats will have a jumper wire that doesn’t go back through the wall to connect to your system. Instead, a short jumper wire connects two thermostat terminals together. What is […]

What is the minimum voltage needed to start a car? Starting Battery Voltage Impacts and Solutions Before Start 11.8V~12.8V / After Start 12.8V~13.2V May not be able to recharge the battery After Start 13.2V~14.8V / After Start >14.8V May damage the battery, check the engine stabilizer How many volts does it take to start a […]

First, identify where each car’s battery is. In most vehicles, the battery is with the engine. Then park the cars close enough together that you’ll be able to connect jumper cables to both cars’ batteries. Be careful, however, that no parts of either car are touching the other. Do all jumper cables work the same? […]

There are two pins that connect a CPU’s power switch. These two-pin connect the PC case’s power button to the motherboard, which turns on the computer. These are the two pins that you need to short circuit. Short circuit two wrong pins, and you might even have a dead motherboard. Where are the power jumpers […]

Like the jumper wire, the 12 volt test light is used to isolate opens in circuits. But, whereas the jumper wire is used to bypass the open to operate the load, the 12 volt test light is used to locate the presence of voltage in a circuit. What kind of component should you use a […]

The 20 AWG Hook Up Wire is available from Remington Industries in both solid core and stranded types. As part of the lead wire family, hook up wire is used in applications such as control panels, meters, ovens, and internal wiring of computers. How many amps can 20 AWG carry? AWG Wire Gauge Chart (1st […]

Types of Jumper Cables Quality jumper cables are made with 100 percent copper wire. Are jumper cables made of copper? These 100% real copper jumper cables are Made in the USA of pure copper with flexible stranding and a flexible, durable jacket material to ensure long life and reliability. What is jumper cable made of? […]

The best jumper cables should be able to harness a hefty dose of power at a reasonable price, all while offering the protection and convenience users need. That means they should be well insulated, have nice alligator clamps or parrot clamps and be long enough to comfortably reach from one vehicle to another. Does it […]

This because until the wire is connected to the first battery, it is not a live wire, will not spark when you touch it to something, is not particularly dangerous. After the return wire is connected to the first battery, it is live, and is dangerous. So you connect it to something safe that is […]

How high can humans jump? Let’s first consider the human jump capacity. Currently, the highest ‘standing’ jump is 1.616 metres or 5.3 foot and was achieved by a Canadian man named Evan Ungar in Oakville, Ontario, Canada on 13 May 2016. How high can the average human jump? Vertical Jump Norm Table rating (inches) (cm) […]

Commonly refereed to as a “Jumper”, “Jumper Bar”, or “Terminal Block Jumper” It is a short length or conductor (commonly copper)that is used to connect two or more points in a electrical circuit. Very commonly used in industrial control panels. Are mainly intended for use with specific hardware, such as terminal blocks. What are terminal […]

An illegal electricity connection is the unlawful alteration of the electrical installation and the electricity transport grid to pay less (or simply not pay) for the energy consumed. This practice has negative effects on the bills of other consumers and on the tax collection of the State. How do I report illegal electricity connections in […]
