If you got 120 volts of current on each leg of a 50amp breaker but only 25v on each wire going into the oven outlet what could be the problem?

It's referring to the electrical service supplying the house. Most homes in the US are supplied by a single phase service, which is often described as a 120/240 Volt system. If your house is supplied by a three phase system, it could be a 120/208 Volt system.
In both these cases you'll be able to install the equipment you have.
NEMA 14 devices are four wire grounding devices. Which means they'll require two ungrounded "hot" conductors (X,Y), one grounded "neutral" conductor (W), and one grounding conductor (G). When installed on a single phase 120/240 volt circuit, NEMA 14 devices can supply 120 and/or 240 volt loads. A NEMA 14-30 device is designed to supply 30 ampere equipment.
The circuit will require a 30 ampere double pole breaker, and four at least 10 AWG copper conductors. You'll connect one ungrounded "hot" conductor to each of the X and Y terminals. The grounded "neutral" conductor goes to the W terminal. And the grounding conductor connects to the G terminal.
You'll need:
- NEMA 14-50 receptacle.
- 40 ampere double pole breaker
- Four 8 AWG copper conductors, or four 6 AWG aluminum conductors (Hot, Hot, Neutral, Ground).
It's common for builders to use a 50 ampere breaker and larger conductors, to make sure the circuit can handle any range the owner's might use. But if you're installing the circuit to support a particular device, you may be able to use a smaller circuit.
It's common to use aluminum conductors for range circuits, because it's a bit cheaper when you start using larger conductors. Type SE (service entrance) cables are common for range circuits, as it's often easier to pull a cable than individual conductors.
In layman's terms. Go to the electrical supply shop, or hardware store. Tell them what you're doing, and ask for:
- A four prong range plug.
- A four wire range cord.
- 8/3 with ground NM (nonmetallic) cable (copper).
- A double pole 40 amp breaker.

You do not note where in the world you are, so this is tricky to answer well. In the US each screw terminal on the 50amp two pole 240V breaker should measure 120V to ground or neutral, and 240V terminal to terminal. At the range itself there should be an outlet with four openings. The two small rectangular pins opposite each other should be about 240V as the meter is showing in the below image, and the rest of the pins should be about 120V relative to each other. If the voltage is off by more than a few percent on any of the measurements, there is probably a break in the wire of one or more pins. With a voltmeter it is possible to read voltage that has leaked from other sources, so low numbers should generally consider to be open circuits.
You may have to trace the wire through the house and figure out what has been done. Often you'll find that some previous owner rerouted it for a new electric dryer or hot tub (if there was a gas stove there and the range plug was unneeded at the time). For your own safety I recommend contacting with a locally licensed electrician for repairs.
