These cords are normally exposed to the elements, for extended periods of time, during use.

As a rule of thumb, the lower the gauge the thicker the wires used and with it, the higher the overall capacity (amp rating) of the cable. The power capacity of any extension cable is influenced by the gauge (measured in AWG) of the wires therein, as well as its length. A 30 Amp cable has the capacity to meet the power requirements of smaller and medium sized (some, not all) motor homes. If you want your motor home’s electrical systems to work properly, when running on external power, you should only use a cable that is capable of meeting its power requirements. Read on to find out why you should add this product to your collection of must-have-RV tools. A 30 Amp extension cord can help you extend the reach of your motor home’s power cable with ease. If your RV’s power cord cannot reach the nearest power pedestal, when you want to use external power, you will need to find an effective and reliable solution.

Good for 230/460V 3 Phase.įor Home/Shop: Use 50 feet of #8/3 or 8/4 cable with 50A 240V Full KVA plug or 3 Pole or 4 Pole Twist Lock Device with proper sized fused or circuit breaker disconnect.

For home or home shop, this amount or overkill is a bad thing.įor Industrial: Use 50 feet of #12/4 cable with pin and sleve device with proper sized fused or circuit breaker disconnect. For an industrial setting, this is ideal. These are only available at industrial suppliers like Ganger or electrical supply houses like Rexel Electric. However, for 460V 3 Phase, I have only seen Pin and Sleeve connection devices used and they are not cheap. These can be found at Lowes or Home Depot without much fuss. You can even use 3 Pole or 4 Pole Twist Lock devices without much issue. Single Phase applications can use 30A 230V Dryer Plugs or Full KVA 50A Plugs without much trouble. I would still use a disconnect or properly sized breaker while still using the plug and recepticle.

The Miller Manual shows the unit wired directly to a fused disconnect. The stranded wire makes this fairly flexible, but no as flexible as Type SO in rubber neoprene, but you won't have to worry about the jacket or insulation breaking down over time due to sunlight, heat, or chemical exposure. For 230V 1 Phase you may need #10 or #8, the #8 would be better, and then for 115V 1 Phase, #6. For your application, #12/3 would cover 230V/460V 3 Phase power options for the 50 foot distance. This is a 3 conductor 75 Deg C THHN Standed cable inside a sunlight resistant/direct burial PVC jacket. We use what is called SDT cable for power feeds on waterwells.

However, it can't be just any #14 AWG cord.

Yes, by the NEC table, and the table in the Miller Manual for for welder, you could use #14 AWG for the 50 foot cord. Most households don't have 460V electricity to them, 230V 4 Wire 3 Phase is more likely since 120V and 240V 1 Phase can be pulled off the lower voltage legs. I only know of one house that has 460V 3 Phase power to it, for Air Conditioning and Waterwell use. My dad purchased this unit this way in the early 80's, usually they have a 10 foot cord instead.Ĥ60V 3 Phase is a different matter. I have never had a problem with it at all. I use a Millermatic 200 that is hooked up for 230V 1 Phase that is equipped with an 8/3 cable 50 feet long with a 30A 230V 1 Phase dryer plug for connection.
