Well, if you’ve planned for future expansions, you may use oversized wires. Otherwise, excessive overheating or other electrical accidents could occur.

Contact a professional regarding how you should install your wiring. The methods do depend on what wire you’re using. The installations can be in a raceway (conduit or tray), buried in the earth, in a cable, or even in the open air. Typically you will find some common installation methods.
This can have some impact on the resistance that your circuit may encounter. Sometimes the wire size may vary depending on the installation method you’re using. If the wire diameter isn’t capable enough to carry the load, the voltage drop would be high. For such long wires, it’s better to get a professional to do this for you. To measure the voltage drop, you could use a voltmeter. However, you should ensure that the voltage drop doesn’t exceed 5% by any means. Usually, a voltage drop from 1 to 5 percent is alright (3% is calculated as optimal).
Even when you’re extending wiring with a junction box.Īs the wire gets longer, the source voltage drops by some margin. That would cause the source voltage to drop. When connecting a place at distance to the source via conductors, there’ll be some resistance in the electric path. However, it’s an essential piece of information that you should know. This might be somewhat of a geeky thing for you to understand. A three-phase circuit can accommodate higher loads better. Single-phase is usually seen in households and three-phase in industries. To identify what phase you’re using, take a look at the number of wires. Whereas, for a three-phase circuit, you’ll need four. For a single-phase circuit, you’ll require three wires. Usually, you’ll see two types of phases: single-phase and three-phase. The number of phases in electricity refers to the distribution of load. But it’s really a very simple term to understand. You may get confused hearing the word ‘phases’ associated with electricity. However, industries might have a different source voltage. We refer to 120V as the standard source voltage in the US and Canada. Source voltage for households and industries may differ from place to place. If you’re expanding your electric circuit, keep the source voltage in mind. These wires should meet your needs if you want to extend your line to 150 feet. To make your a little easier for you, here are our top picks for these wire sizes: Spartan Power 2/0 AWG 20 FootĤ/0-4/0-2/0 Aluminum SEU Cable 600V Service Entrance Wire (50FT)ġ/0 Gauge 1/0 AWG 10 Feet Black + 10 Feet Red Welding Battery Pure Copper For a three-phase power source, 1/0 AWG Copper wire or, 3/0 AWG Aluminum wire can be used. We recommend you to get 2/0 AWG Copper wire or, 4/0 AWG Aluminum wire for single-phase. If you want to pursue an expansion of 150 feet for your 100 amp service. Both have their own characteristics, but you need to choose the one that fits your needs. Aluminum is very lightweight and easier to work with as it’s flexible. However, two of the most popular and practical ones are copper and aluminum.Ĭopper has a higher conductivity than aluminum. If you have some knowledge about conductors, you know that not every conductor has the same conductivity. Now in order to choose the right wire gauge size, you need to know about conductor type. Let’s briefly discuss these topics, shall we? Type of Conductor This is why you need to know some key factors before choosing a wire-įor example, the right type of conductor, voltage for your source, minimum voltage drop, the installation method of your circuit, number of phases, and so on.
Especially, if you don’t have adequate knowledge about electrical calculations. Similar to picking 12-2 wiring for lights. Conclusion Calculating Wire Size For 100 Amp Service 150 Feet – Factors To ConsiderĬhoosing the right wire size for your amp can be a huge hassle.
