A wired nut
On what? IS this an outlet or a switch?
Two wires are needed for 220 volts.
To install a new fixture to replace the one that was removed reconnect the two hot wires together and then reconnect the two neutral wires together. Place the two wires from the new fixture to the corresponding wire colours that you just spliced together. This wiring should be down stream from the light switch. When the switch is turned on the new fixture should light. If this is not the scenario of your question then more information needs to be given.
The better quality tools all have 3 wires. You are looking at cheaper tools.
If you mean 2 bare copper wires those are the ground wires. Tie them together and then connect the light fixture ground wire which will be green or bare copper to those ground wires.
what do we call in the two sided fastener
A wire nut or terminal block is commonly used to join two electrical conductors in order to securely connect them and prevent electrical contact or short circuits.
A connector or a fastener can join or link two things together. Examples include screws, nails, bolts, nuts, clips, rivets, adhesive, or stitching.
A dryer needs four wires for proper operation and safety because it requires two hot wires, one neutral wire, and one ground wire. The ground wire helps protect against electrical shocks and ensures proper functioning of the appliance. It is a standard requirement to have all four wires for dryer installations to meet safety regulations.
Yes, the hook and loop structure of a velcro fastener is a solid structure.
A screw is a type of fastener that consists of a threaded shaft and a head. It is used to join two or more surfaces by rotating it into a pre-drilled hole. Screws come in various sizes, shapes, and materials to suit different applications.
Yes, especially if they are similar in construction or related. The semicolon is the proper way to join them.

No, you should not connect two wires to one lug in a panel board. Each lug is designed to accommodate only one wire in order to ensure proper connections and to prevent overheating. If you need to connect multiple wires, you should use a wire nut or a junction box to splice the wires together before connecting to the lug.
Assuming there is 8 wires in existing Renault wiring iso speaker plug at back of radio, the two outer wires at each end of plug are for left rear and right rear speakers, tap into these wires i.e. strip the insulation back a couple of inches from the plug and join new speaker wires onto the stripped wires. If only 4 wires in existing Renault wiring iso speaker plug then buy iso speaker plug from auto factor and join existing Renault wiring on speaker plug onto new cable and join new speaker cables (the ones you are fitting) onto the outside wires at each end of the new iso plug.
In a box it is common practice to join two black wires, two white wires and two ground wires, for example, to extend the circuit to another location. Provided you don't overload the circuit it is okay to put 3-wires into the comparable wirenuts for your external light. There are some added caveats including not exceeding the number of wires designed for the box (usually 4); and outside circuits normally require a GFCI circuit for safety.
When you join two 12-volt wires together, the voltage remains 12 volts, as voltage in parallel connections does not increase. If the wires are connected in series, the total voltage would double to 24 volts. However, if both wires are connected to the same power source correctly, they will function normally without any issues. It's important to ensure that the wires are connected properly to avoid short circuits or overloads.
