14 AWG Power Cord for 240V


I posted several weeks ago about a european machine we purchased. We received the machine. Rather use an adapter to convert the Italian 3 - prong plug style we decided it best to use a new plug and recepticle. We installed a new 240V single phase 20 Amp circuit to the machine. The power cord we have is rated for 300 V (per the labeling on the outer cover), but the modular plug that fits to the machine states 125V. It looks identical to the 250v modular plug that shipped with the machine. Do you think I can use the 125V plug on the machine side, even though we will run 240V service? It is very low amperage, only 3.4 Amps

Thanks
AP

14 AWG Power Cord for 240V


you need to use equipment that is rated for the voltage. If you are using 240 volts, you need to use equipment rated for 250 v.

can you post a pic of what you have? you should not be able to plug a 120 v plug into a 240 volt recep. They are configured differently so that cannot happen.

that is, unless the configuration is European.

Perhaps I did not communicate clearly...
The device was shipped with a Universal Power cord. This cord is an 18AWG Modular to 3-prong grounded Italian plug. We have installed a 240V NEMA 6-20 recepticle and plug to match. We cannot simply cut the plug off the universal cord they shipped with the machine because it will then be too short. So we have on-hand a 14AWG universal Power cord rated for 300V (the outer sheath of the cable states 300V max). We will simply need to cut the plug (standard 3 prong US 120V plug) off the heavy duty cable and installed the NEMA 6-20 plug. The question I have is the modular end of this cord is molded and rated for 125V. But it is substantially more heavy duty than the modular connector shipped with the machine that is rated for 250V. If we simply replace the male plug on the end of the 300v UPC and keep the modular female plug to attach to the machine will this be OK? Even though it is stamped for 125V.

Perhaps this better explains...

Previous thread - Italian Machine with 230v Electrical Connection


you need one of these. - http://www.cables.com/Products/NEMA-...C13615P-6.aspx, and a "NEMA 6-15R" Receptacle installed, connected to a 15A 2 Pole breaker in your panel

EDIT - That cord will plug into a 6-20R Receptacle as well.

I don't think it will... The NEMA 6-20 plug we have is a twist lock style with the pins in a circle on the plug

The twist lock style is annotated with a L before the designation, ie L6-20R, 6-20R designates a straight blade receptacle.

here is the cord you need
