The increase in voltage from the main panel to the sub panel may be due to the resistance in the wires within the electrical system. As the current flows through the wires, there may be a voltage drop across the length of the wires, which can result in a slight increase in voltage at the sub panel. This phenomenon is known as voltage drop.

What is the main power feed for a house?
The main power feed for a house is typically provided by the local utility company through overhead or underground electrical lines. This feed connects to the main electrical panel in the house, which distributes electricity to the various circuits and outlets in the home.
If you have 100 amps on the main switch and there is two swiches with a pin is this not then 200 amps?
No, having two switches with a pin does not increase the total amperage available. Each switch can control a portion of the total 100 amps coming from the main switch, but the total available amperage remains at 100 amps.
Does a sub panel need a ground conductor from main panel?
Yes, a subpanel must have a separate grounding conductor running back to the main panel to provide a safe path for electrical faults. This grounding conductor is in addition to the neutral conductor and helps prevent the possibility of electric shock and ensures proper operation of circuit protection devices in the event of a short circuit.
How many 50 amp breakers feeding 50 amp outlets can you install from a 125 amp main panel?
You can install a maximum of two 50 amp breakers feeding 50 amp outlets from a 125 amp main panel. Each 50 amp breaker is using half of the available amperage from the main panel.
What is the largest sub panel you can install off from a 60 amp main panel fed by 100 amp service?
You can install a 100 amp sub panel off a 60 amp main panel fed by 100 amp service. This allows for the sub panel to be adequately powered with headroom for future circuits or expansions. It is important to ensure the wire size from the main panel to the sub panel is sufficient to handle the load.
What is the cause of 150 volts on a 120 volt?
Usually it is caused by a faulty ground at your main panel.
What are the steps in upgrading 120V 15A to a 240V 60A air condition panel?
You have to find Line 1 and Line 2 to get your 240 volts. Both do not exist in a 115vac panel. If coming from a main panel, you would install a 60amp 2 pole breaker and then run heavier wire to the a/c unit. A sub-panel could be added if no spaces are left tin the main panel.
What is the rating of the main circuit breaker of the 105kw power distribution panel?
To answer this question a voltage must be stated. Main breakers are rated in amps. This is the formula for amperage. I = W/E. Amps = Watts/Volts. As you can see a
When would you want to upgrade the main electrical panel vs just adding a sub-panel?
Depending on how many breakers you have in your exisiting panel if you only have a old 6 or 8 circuit panel then I would suggest a new panel, In the newer building world where you have a 20 or 30 circuit panel then I would suggest a sub panel.
How many volts can Pikachu store?
pikachu can store 75,000 volts and raichu can store 100,000 volts.the only reason ash's pikachu beat a raichu is because it is the main Pokemon.if it was a real battle and pikachu wasn't the main character's Pokemon raichu would beat him by 25,000 volts.
Why is it that you get a reading of 120 volts from the main breaker but it wont power a lightbulb?
This is the type of reading that you would get with an open neutral.

What type of Breaker box should you buy for a For a RV That calls for a 30 amp breaker?
An ordinary twelve circuit distribution panel will do the job. The internal wiring of the panel will be different than when the panel is used on a home three wire system. When RV's connect into the 30 amp power receptacle in RV parks the voltage is only 120 volts. To utilize the whole distribution panel you are installing, a #10 jumper wire is connected between L1 and L2. This can be installed ahead of the main breaker where the power cord connects to the panel box. With this jumper in place both sides of the distribution panel will receive the 120 volts. No 240 volt equipment will be able to operate from this panel, as there is only one "hot" wire feeding it.
Where is the proper location for a main breaker in a panel?
Normally the main is on the top but you can install a service panel with the main on the bottom unless local codes prohibit it.
What is the formula for winding transformer?
the formula is (no. of turns at main)/(no. of turns at out)=(In volts)/(out volts)
