Yes, with a caveat. The 50A wire and plug is more than heavy enough for the dryer, so there is no problem there.
The possible problem is that the dryer is designed to be protected by a 30A breaker. In the event of failure in the dryer, the breaker may not trip as it is oversized. The best solution? Get a small breaker box from a home center and mount a 30A breaker in it. Mount it on the back of the dryer, run the 50A cord into the feed lugs of the box, and connect the dryer feed to the 30A breaker. This way you can plug the dryer into the 50A outlet like you want, and the dryer is protected with a 30A breaker as usual. You can get small breaker boxes or fused disconnects without too much cost. Just make sure the breaker box / disconnect panel is rated to 50A, as you want to feed it off a 50A circuit.
As long as the voltage requirement of the dryer matches the voltage of the outlet (which is presumably 240 volts), then yes. The amp rating of the cord and outlet is merely the maximun current (amps) allowed. You're well under that with 24 amps.
US NEC: No. You must plug 50A rated equipment into a 50A circuit, not into a 30A circuit. In fact, since the plug is physically different, you will not be able to do so even if you try. Do NOT attempt to replace the pigtail. The code requires that running current load not exceed a percentage (80% ??) of breaker capacity, and the 50A equipment will certainly exceed that.
If you are asking if you can replace a 50 amp circuit breaker or fuse with 30 amps, the answer is yes. However if your load is drawing more than 30 amps the breaker will trip and the fuse will blow. You can go down in rating, but not up unless you ensure wire sizes and devices are specified for the higher amperage.
The 50 amp range cord has a different blade configuration than a 30 amp cord. To keep your house insurance intact, do not try and go against what are recommended practices. For the sake of a few dollars buy the correct dryer cord and be secure that you have a safe installation.
No, the pin configurations are different.
It depends, the current draw is as follows:120VAC - 27A208VAC - 15A240VAC - 13ANo it would not, the appropriate plug would be:120VAC - 30A circuit, or 50A depending on if it will have a high duty cycle.208VAC - 30A circuit, unlikely unless you have 3-phase power240VAC - 30A circuit, NEMA 14-30 if you have split phase power (ie: if in a home)AnswerAs the question refers to a '13-A' plug, then it's reasonable to assume that the questioner is referring to a British wiring system, in which a '13-A' fused plug is the name given to the standard 230-V plug used in a UK residence; the '13-A' refers to its rated current. Reference to the UK's Wiring Regulations will give a definitive answer.If you apply the equation for power (P =UI) the you will see that the maximum power that it can supply to a load is: P = 230 x 13 = 2990 WFrom this, it is apparent that a 3200-W load would be 'pushing it' and will likely operate the plug's fuse within a short period of time.
yes
Assuming a 120V circuit then a 30A Single Pole. For a 240V circuit an 30A two pole. Of course anything smaller that a 30A is acceptable. 30A is the maximum allowed.
Yes provided the voltage is compatible.
No, the amperage pin configurations are different between a 15 amp and a 30 amp plug.
The outlet is rated for 30A, so anything up to, but not exceeding 30A can be plugged in.

Probably not, the pin configuration of a 30A dryer plug should be different from a 15 or 20A A/C plug. The demand draw of a dryer is higher than that a A/C unit and would trip the 15 or 20A breaker. By putting a bigger breaker on the A/C circuit would not be a good idea either because the wire size to the A/C plug would then be under sized.
for USA, Canada and countries running a 60 Hz power supply service.If the current draw through the circuit is less than the rated current of the circuit then there is no problem. In this case if it is a 30 Amp dryer fed through a 50 amp outlet on a pigtail that has a 30 Amp plugplugged into a 30 Amp outleton a circuit protected by a 30 Amp breaker No worries! It is wise to place an over-current device (fuses or circuit breakers) in your pigtail, though.-EDIT- Only if it's a 50A outlet. If you have 50A wiring on a 30A breaker you are quite safe.As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.Before you do any work yourself,on electrical circuits, equipment or appliances,always use a test meter to ensure the circuit is, in fact, de-energized.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
It would have to be a 30 amp breaker to use the full power of the welder. I'd say go with the 30A. The general rule is that your planned load should only be 80% of the circuit capacity. That means a 30A circuit should have a maximum load of of (30*0.8) = 24A. With the 30 amp breaker you must have at least #10 wires feeding the circuit.
Unless something is wrong with the circuit, no. It is the voltage that matters. The device will only draw as much amperage as it needs. If the power supply has a problem, it is possible that the extra amperage could translate into more voltage, but this is unlikely.
It's not advisible but depending on what condition your equipment is in it might be possible at least temporarily. I would strnogly discourage leaving it unattended for long.
If the motor starts without tripping the breaker and when the motor picks up the load and the breaker doesn't trip, just leave it. Code states that motors should be protected by 2.5 times the FLA to allow for start up inrush current which can go as high as 300%. In this case 14 x 2.5 = 35 amps. There not being a breaker of that size go to the next highest, that being a 40 amp breaker. The motor should have additional overload protection on the circuit set to the FLA of the motor and not depend on the breaker to provide overload protection.
