240v 50A on the same line as a 50A RV outlet

The bad news is, you need 2 cable runs, two 240V breakers, and a UL listed interlock in the panel. The good news is, we can do this thing with sensibly priced aluminum heavy feeder. …

240v 3 prong - no voltage with neutral

Yes, this is a lost neutral or ground. Keep in mind that if this is a NEMA 10 type receptacle, hot-hot-neutral (no ground), then a lost neutral is a rather dangerous situation. Such connections typ …

Change a NEMA 6-15 plug to fit an NEMA 14-50 receptacle

You can't do that. You can't put at 50A plug on a 15A appliance. What you can do is change the NEMA 14-50 to a NEMA 6-15. You will also need to change the breaker in the panel, and will need to p …

60Hz to 50Hz Conversion

The input voltage does not matter, so bonus points if you can find one rated for 120V-240V input, and the ability to input varying voltages strongly suggests it is a double conversion unit. …

Two 20 amp circuit breakers installed with copper wire bridge

If the breakers are powering device(s) that use both 120V and 240V (classically ovens (for the light) and dryers (for the motor)), then that device requires common-trip. … If the breakers are powering a variety of loads, every single one of which is a 120V-to-neutral load, or every single one is 240V-only (no neutral: water heater, A/C, EV charger), then common trip is not …

Can I replace a outlet dedicated 16A/240V with a 20A/125V outlet

Your service panel is in Israel and it is 220/230 volts AC, which is the standard power there. 120V is not available in Israel. This type of outlet you linked is called a NEMA 5-20. It cannot be used …

Can I connect my EU 230V 2.8kW appliance to a US 240V 20A receptacle?

blink blink I can't believe it. We get so many variations of "I got this European thing" or "can I plug (huge thing) into (tiny outlet)" or "renting as complication" - and the answer is always a huge …

Can I power a german 240v spindle motor off of a USA 240v nema5-50 welder plug?

Nope, you must put a 240V 15A plug on the cord. (NEMA 6-15). … Then, install a 15A/240V circuit with NEMA 6-15 receptacle(s)... or a 20A/240V circuit with NEMA 6-20 receptacle(s) (which will accept 6-15)... or a 20A/240V circuit with 2 or more NEMA 6-15 sockets (e.g …

Running a 50amp 240V line 300 feet to a shed

First, forget 3% That's just the wire size calculators trying to upsell you on wire. Notice they also default to copper :) 3% isn't that important. And NEC even says so; it's an informational note t …

Grounded properly?

It looks to me like the box is installed flush with the back of the drywall. You will need to add a "mud ring" to that which is the thickness of the drywall. That would bring it out to a normal 1-gan …

3-Wire Dryer Connection Works with Dryer at Home, But Not At Other House--socket tests ok th...

That is why neutral reads 0V from one hot and 240V from the other. And it's trying to kill you. So what do they do to "ground the chassis" on these obsolete 3-wire connections? …

Adding a 240v circuit-keep me alive

The only way you can use a 30A/240V socket is with a PDU. (and if you have a 30A PDU, that's fine, go for it, however...) … You can only power 240V devices, even if you had a PDU. I propose a 20A multi-wire branch circuit (MWBC) This gives two complete 120V legs on 1 cable, and also supports 240V loads. …

How do I wire a single phase 240v APC UPS from US split phase power?

Whether you need neutral or not, a 4-wire NEMA 14 connector is always OK, and provides the most versatile socket (it will support 120/240V loads also). …

What is the best wiring for NEMA 14-50 receptacle in a 240V country?

This is correct for 240V between the hots, no neutral, and ground. Then why the bleep do EVSE's all use 14-50 and not 6-50? Darned if I know. …
