Does it matter if a 30A dryer is plugged into a 30A outlet through a 50A pigtail?
- fed through a 50 amp outlet on a pigtail that has a 30 Amp plug
- plugged into a 30 Amp outlet
- on a circuit protected by a 30 Amp breaker
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.

Does leaving the switch on to a switched outlet use electricity if nothing is plugged into the outlet?
Is it better for your battery to keep your laptop plugged in all the time or let it die then charge it?
Generally, no. We usually try to avoid having a lot of things plugged into one outlet, which is the usual meaning of "octopus connection" when we talk about things electrical. If we get a lot of stuff plugged into one outlet or a single outlet strip, we could approach (or exceed) the current rating on the outlet and end up tripping a circuit breaker. Less things plugged in is better.
Yes, a space heater can be plugged into any outlet. Depending on what else is drawing current on the circuit will govern whether the circuit will trip or not. If the heater is plugged in and the circuit does not trip it can be left plugged as long as it is needed. If the heater trips after a few seconds, then try another outlet.
You can't plug Hz into a socket outlet. What you get from an outlet is a supply of electrical power with a fixed voltage, a fixed frequency (50 or 60 Hz depending on the country) and a maximum allowed current. The equipment plugged in must be designed to operate at the same voltage as the supply voltage. With some equipment it doesn't matter if it's 50 or 60 Hz, with other equipment it does matter…
The fuse is what restricts how much current you can draw from an outlet. If you have the wrong fuse you can draw more power than intended from an outlet - but only if the appliance plugged in can use it up. To get too much power out of an outlet, with a suitable appliance plugged in, then you also have to have a higher voltage in the outlet. And for that to happen, something…
When running outlets in a series can you still use the outlet itself as a coupler or do you have to pigtail the wires then feed the outlet?
Situation: You have been told that your office will be moving. You check out your new area and notice that the LAN connection for your printer is across an aisle and there is only one outlet in your area. You have numerous electrical devices that must be plugged in. You decide to run your LAN line across the aisle and pigtail surge protectors to accommodate all of your electrical devices. What dangers are posed by…
With regard to the power cord that connects your laptop to the outlet is it dangerous to disconnect only the end going into the computer while leaving the other end plugged into the outlet?
There is a couple of things going on here. First a 30 amp dryer plug will not fit into a 50 amp range plug. So rather than changing the the dryer cord over to a 50 amp range cord all you have to do is change the 50 amp breaker over to a 30 amp breaker in the distribution panel. The wire size is big enough to run the 30 amp dryer. Change the 50…
Any outlet that is on a wall or counter back splash that is used for your convenience to plug in anything that is to be used in a temporary situation such as a toaster, mixer, radio etc.is a convenience outlet. All 120 volt outlets, in the US and Canada, that are not designated for a specific usage. On the other hand a designated outlet is for a specific usage such as for a washer, dryer…
