When we measure from hot to neutral we get between 40 & 50 Volts
I am assisting my sister and her husband with some fix-it problems. When we measure from hot to neutral, or ground, we get between 40 and 50 volts on a receptacle we are testing on an enclosed patio where they have not had power since they bought the house in 2006.
The house wiring is a mix of old two wire service without ground and current three wire service with ground. The breaker box is a mess. I am concerned for their safety.
I am looking for the wiring logic that would show only 40 to 50 volts on a circuit. There are also other examples of low voltage readings at other locations in the house.
Our friends at Lowes, Home Depot and Menards have been of little help other than an open neutral or ground. To my understanding, if there is no ground or neutral, there is no circuit and no voltage.
Re: When we measure from hot to neutral we get between 40...
This is "phantom voltage." To be sure of this you can try shorting the hot with the ground. Should not short. The voltage isn't dangerous. It often happens when two hot wires are in the same cable. For example a 12/3 romex with a shared neutral. When one hot wire is turned off and the other is still energized, voltage can leak from one wire to the other, causing a reading of 50 or so volts on the non powered wire.

I would recommend checking the meter to make sure it's set for AC.
If it is set on DC the meter will show an inaccurate reading.
There are polarity testers available @ places like home depot, etc.
it's usually a small yellow plastic block with 3 LEDs showing hot, neutral & ground with "prongs" so it can be plugged into any wall plug.
it's a quick & easy way to find out the status of an outlet.
a 6ya expert can help you resolve that issue over the phone in a minute or two.

Freezers are not measured in horsepower, only mechanical engines. This is the specs, and it is basically a 25 amp freezer, with an additional 7 amps or fans lighting and door heater, both at 250 volts AC. However, running an Amps to HP converter gives 6.971 horsepower.
It requires two hot wires measuring 240 volts across them and 120 volts from either of them to the neutral connection. Some people refer to the two 'hots' as 'two-phase' and some refer to it as 'single-phase'. At any rate, you do NOT have three phase requirements with that dryer.
Most of the dryers have a 120volt motor which is why you need two hots and a neutral. To complicate matters, recent changes to the code now require 4 wires on newly constructed structures. Two hots, a neutral AND a bare ground wire.
all trailers use 120 volts a 30 amp cord 3 pronged is wired a hot a neutral and a ground a 50 amp cord 4 pronged is 2 lines of 120 volts but its not 220 volt it has 2 separate 120 volt hot lines a neutral and a ground you should see a dealer to explain for safety
Look at rating plate on side of unit for Volts, Amps, Watts. Volts x amps = watts. If unit is 240Volts, then you need double-pole 240Volt breaker If unit is 8500 watts at max power, then 8500 watts divided by 240Volts = 35 amps.
What size breaker for 35 amps? When electricians figure load rating for breakers, they use the 80% rule. 40 amp breaker x 80% = 32 amp safe maximum load for 40 amp breaker. Use 8 gauge wire with 40 amp breaker. 50 amp breaker x 80% = 40 amp safe maximum for 50 amp breaker. I use 6 gauge wire with 50 amp breaker. 60 amp breaker x 80% = 48 amp safe maximum for 60 amp breaker. Again, use 6 gauge wire with 60 amp breaker.
How to connect wires to unit. First of all, all outdoor HVAC units require power cut off located next to unit. This lets the mechanic, or service tech turn power off to work on unit, even if the mechanic does not have access to main breaker box.
Next, open unit to see where wires connect. If unit has wires, then connect both hot wires from 240 breaker to the wires inside unit. Connect bare ground wire to green ground screw. If unit has terminals. The terminals will be labeled L1 L2. Connect each hot wire from 240Volt breaker to either one of the screw terminals. Then bare ground goes to green ground screw.
Copy following links for basic illustrations connecting wires to terminals, and to breakers, and selecting wire size. http://waterheatertimer.org/How-to-wire-Tankless-electric-water-heater.html
You probably need to use a full synthetic motor oil. Use JASO MA certified 10W-40 or 20W-50 . I use Amzoil 20W-50 and it solved the problem of not being able to find neutral in rush hour traffic when the bike gets really hot.
Please try the following: 1# Turn on the main power switch(ON/OFF) & press 15amp & 3amp circuit breaker at the same time to re-set the breaker.2#With line voltage is present at ''Main'' 15amp circuit breaker,Check connection between circuit breaker & power switch(ON/OFF).3# Verify line viltage is present at the power supply input connectior 44,(Brown=hot,Buue=neutral).4# Check connection between power switch & 15amp circuit breaker.Hope this will help you.
Hello. I can assist you. first of all, please do not use a 50 amp plug on a dryer. A dryer requires a 30 amp plug. The plug you are using is for an electric range or oven. The black and the red wires are both hot wires. The white is neutral and the green is ground. read the device it will say LINE and LINE for the hot wires and neutral for neutral. It should have a green screw on it for your ground [green].
Assuming you are testing alternating current and not direct current that sounds quite normal. Plug with confidence. You are using equipment designed for 110v-120v and you're getting 113.8v where it matters most. Higher voltage to ground is nothing unusual, that's just how this inverter is designed.
You have Red and Black HOT wires and a Green Neutral - That is 220 volts. From the wall - Black is Normally HOT and White is Neutral. That is 110 volts. If that is a typical household outlet, is will only supply a demand at about 15 amps while running at 110 volts. Your Cooktop will most likely demand somewhere around 50 amps at 220 volts. - Short Answer - You will need to have a 220 volt supply line ran to the cooktop from the breaker. Easy to do but dangerous if you are unfamiliar with high voltage.
