Check the battery voltage on your tester. The voltage on the panel is the same throughout the whole electrical system.
Answer for USA, Canada and countries running a 60 Hz supply service.Yes, you have to have a ground rods connected to the system. This is especially important in North American systems as a split phase is in use. The center-point winding by code must be grounded. This is a backup in case the neutral conductor becomes open. If this backup was not in place, due to the configuration of the distribution panel, 240 volts could be applied across two 120 volt loads which would be a series connection. If the resistance across both of these series loads is equal nothing will happen as the voltage drop would be even at 120 volts. If the series load resistances are not even then uneven voltage drops will appear. This could cause higher that allowed current to flow through devices that would damage them. Periodic maintenance of the ground rod connections should be done by every homeowner to make sure the connections are clean and tight.
First off, this is for a single phase 120/240V system only. The ground and neutral can be bonded at the receptacle but not instead of bonding them at the panel.You should always have them bonded together at the panel in a single phase 120/240V system. Otherwise you risk having a floating neutral in your system.
600 volts
Answer for USA, Canada and countries running a 60 Hz power supply service. No it is still 100 amps. The two switches are 100 amps each but they protect the two separate legs, L1 and L2. If this is a main service the electrical code states that if either leg L1 or L2 trips both legs feeding the panel will shut the power to the panel completely off. If this is a separate load off of the mail panel which it sounds like it might be, because of the pin between the two breakers, the same rule still applies. L1 to neutral is 120 volts, L2 to neutral is 120 volts and L1 to L2 is 240 volts.
If it was preinstalled, it may have been adequate at the time of installation. It depends on the power requirements of the home. If this is a new install, the NEC has a minimum of 100A for service equipment. To be honest, I would install 200A minimum to allow for future expansion.
Usually it is caused by a faulty ground at your main 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.
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
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.

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.
This is the type of reading that you would get with an open neutral.

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.
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.
