Indoor & Outdoor Extension Cords

I found a couple of calculators online and one of them says the minimum wire size for a 150' 13A run is 8awg. Yes, other things, like a garage light, or some other appliance could be on the same circuit you've plugged the extension cord into. You also want to use two gfi's rated for 20 amps they are the ones that have the sideways slash in the receptacle. There is much confusion about extension cords. I had no idea there were so many considerations in using a heavy duty extension cord, as in using outdoors for my hedge trimmer.

But this is how you can temporarily use a 20 amp device in a house that has electric dryer but only 15 amp circuits But some web pages I've visited give me slightly differing opinions. I've seen 3-5% used, which actually matters at higher amps and distances. I usually try to get the electricians to turn on an outlet for me. The 16 gauge worked perfectly for the 13. What Load Can Each Gauge Wire Handle? The welder would not be drawing 20 A constantly.

150' Extension Cord

Tim, a couple of other things about extension cords: 1. The link below should help anyone wanting the same information. That is, the cord with the largest wire in it should go first then progressively smaller. As a wire gets thicker it can carry more electricity amps. There are no 2 identical fuses. The green arrow points to the amperage of this professional circular saw. I'm trying to run an outdoor speaker system for a party; two tower speaks requiring 6 amps each.

I used the 16 gauge 100' for a 13. Usually if I need something that long I'd go and get the reel of cable and make my own similar to the looks of that one I linked to and I've made my own extension cords with boxes on the end like that before. It does not calculate power watts. Electricity encounters resistance as it travels through electrical wires. Could you please explain your rationale? Go slowly at first and you may not feel much. I use upwards of 200' of extension cord sometimes, but only to bring power to my laptop or a cordless drill charger.

Hi Tim, As always, thanks for good, useful information. A 12 gauge wire is rated for 20 amps. You just have to be sure the cord is large enough to handle the loads. Why Does my Circuit Breaker Trip With the Right Cord? This article is particularly helpful for keeping people and their tools safe! Then the smaller cords would introduce the drop still. Thanks Sean for your blunt comment. They have been like that for over a decade and still work fine. Ohm's law is a physics principle that helps keep you safe with electricity.

I normally plug the welder into the laundry room outlet, which is a dedicated 20a circuit, in a house built in the 50s. Recently my brother and I found mom had cheap extensions, some daisy chained throughout her house in practically every room. Determine the amperage of the tool s being used. Note: All fuses were same manufacturer and configuration. The higher the resistance the more power is dropped across the extension cord. If you have to use multiple cords connected together to get the length you need and assuming they aren't all the same size, you should connect them in descending order. If the fuses at the motor controller were the same value as the fuses at the bus duct, the fuses at the bus duct would invariably blow.
