What type of wire do most homes use?
Most houses use copper wires for wiring installations, including sub-panels and other electrical components. Bigger infrastructures, including electrical posts, use aluminum wires instead of copper.
Why use copper wire instead of aluminum wire?
Another factor why you should consider choosing copper wire instead of aluminum wire is that copper wire possesses high tensile strength — meaning it has much higher resistance and protection against breakage. It also expands less at high temperatures compared to aluminum.
Why is copper wire used in modern homes?
Copper wires are extensively used in modern houses and infrastructures due to the wire’s great conductibility and stability. Its stability and effectiveness in conducting electricity cannot be closely compared to aluminum wires or any other material, giving copper the best output when talking about efficiency in power, next to silver.
Why is aluminum wire used?
Due to abundance, the use of aluminum wire, although less conductive, is widely accepted because it offers a cheaper cost, unlike copper wire. Sacrificing a little bit of efficiency for the purpose of economical gain may be a tough call but a worthy shot.
What should be the top priority before doing electrical installations?
Aside from fire safety, your physiological safety should be the top priority. In other words, before doing any electrical installations, you should be attentive to things like:
Is copper wire safe?
Copper is generally safer to use in electrical installations such as sub-panels because compared to aluminum, copper does not expand easily like aluminum wires when current runs through the wires.
Is silver wire better than copper wire?
Silver wire is a better choice in electrical conductivit y than copper, but it is not widely used in houses and other buildings or infrastructures due to its disadvantages in other properties, such as a lower melting point compared to copper and a higher cost than any other usual conductors we are using.

Can you run a 100 amp subpanel off a 100 amp main panel?
Furthermore, can you run a 100 amp sub panel off a 100 amp main panel? To the best of my understanding, there is no code issue running a 100A subpanel off a 100A main panel , so long as the wire size is correct, and the installation is correct. For a subpanel, you need four wire service (two hots, a neutral, and an equipment ground).

As a reminder, your feeder will be 4 wires, the two hots and the neutral will be #1AL (unless you've de-rated the neutral to 70% or from specific load balancing calculations if that is allowed in your area).
How far from earth should aluminum grounding conductors be installed?
NEC250.92: Where used outside, aluminum or copper-clad aluminum grounding conductors shall not be installed within 18 in. (457 mm) of the earth.
How to determine wire size for sub panel?
When planning the wire size for a sub panel, or any panel for that matter, it is important to factor in the length of the distance to the panel from the source, and the amperage of the sub panel. The circuit loads placed upon the sub panel will determine the size of the sub panel as well. So basically, everything starts with planning the load that will be placed on the sub panel, and then we calculate the wire size feeding the sub panel based upon the distance. It is also important to factor in any electric motors that may be used due to the starting load which will effect the amperage and the voltage.
What is sub panel planning?
Planning for an Electric Sub Panel: Identifying Panel Circuits and Connected Loads. Sub Panels are installed and used for several reasons including expanding the circuit breaker capacity of the main electrical panel.
How to upgrade a 200 amp meterbase?
You might want to upgrade your 200 amp meterbase to a double lug 325 or 400 amp meterbase. Then run the feeders that are existing from the dwelling panel to one set of lugs in the meterbase. Then run either 2/0 cu. or 4/0 al. three wire feeder directly from the meterbase and without a disconnect or service panel until you get to the detached shop . Just run the feeders directly to the new shop structure from the meterbase non stop. Then make sure your main 200 amp breaker in the shop is nearest point of entrance of the structure and install a ground rod or other approved new grounding source to serve your building.

Can you run 240 volts on a transformer?
If you are running 240 volt you shouldn't have to worry about a voltage drop problem unless you are carrying that 240 volts more that 250' from the transformer to the separate structure 75' away from the main dwelling. If you exceed the 250' from the utility company's transformer then come back in and we will try to provide a demand load of your shop and the voltage drop expected to be experienced for you.
