    Make sure you push the handle hard to the off position (this resets the breaker handle) before you push the handle back to the on position.

My electrician buddy says never turn off the main on the weekend.

Main breakers are subject to heat for a long time. Heat shortens the life of all electrical devices.

Click main all the way to one side, and then push back
If it doesn't engage, then the breaker is probably bad

Square D circuit breaker in a home fuse panel and I have already replaced the breaker with a new one.

i strongly recommend that you get in an electrician to investigate the problem
from your description of the amount of power required from your circuit breaker I would consider that there are to power wires from the back of that unit
one circuit to run half the points and another wire to run the rest
If only 1/2 are working, I am thinking that one of the wires at the back of the breakers is loose or come undone/broken and that will require the services of an electrician
To further explain this line of thought, each circuit in a house is designed to carry a maxim of 10 amp total (wire current capacity) so that with all outlets in operation the maximum current is 10 amps
if the required current allowed exceeds that the electricians break the numbers up so that a second circuit is employed again up to 10 amps max
if again there was a requirement that exceeded the 20 amps ( circuit breaker amp) a second circuit breaker would be installed and a 3rd circuit and so on

Main breaker can't be stitched back on after neighborhood power outage in our home, yet all the neighbors have power except us! Why are we the only ones without power?

You're trying to load the entire house on the main breaker all at once. There significantly less stress on the main breaker if you start it like this:

1) Shut off all the circuit breakers.
2) Turn on the main circuit breaker.
3) Turn the other circuit breakers on, one at a time.

Good luck!

Robinar Cooltech 342000 - on start up stops on the "Initalizing System" screen. Is there a reset procedure available?

You can try the following : 1# Check main 15 amp circuit breaker (located on back of the machine), reset the circuit breaker. If breaker tripped again after reset, the circuit breaker need to be replace.
2# Verify line voltage is present at input of main power switch & output at switch turn ON. If line voltage is not present at power switch input, check connections between power switch and AC plug. If line voltage is present at power switch input, but not at output with power switch turned ON, replace power switch.
3# If all proceeding steps tested OK & problem still exist, you may nee to replace The main control module.
Hope this will help you, if so please vote for it.

My 200 amp braeker(main is tripped and wont reset. What should the incoming voltage be???

Don't mess with main breaker if you're not qualified.
Wires on main breaker are Hot even when main is turned off.
The only way to turn off main is to pull meter.

1) There are 2 Hot wires that connect to main breaker.
Each wire is 120Volts, and each 120V line is 'out of phase' with the other.
Two out of phase 120V lines create 240Volt circuit when they are wired together.
Read more on links below.

2) It sounds like your main breaker needs to be replaced, unless total of all circuits exceeds 160 amp. Turn off small circuit breakers and try main breaker again. If main resets, then turn small circuits back on one by one. Your main may still be bad.

Please do the following : 1# Check main 15 amp circuit breaker (located on back of the machine) it may tripped, reset the circuit breaker. If breaker tripped again after reset, the circuit breaker need to be replace.
2# Verify line voltage is present at input of main power switch & output at switch turn ON. If line voltage is not present at power switch input, check connections between power switch and AC plug. If line voltage is present at power switch input, but not at output with power switch turned ON, replace power switch.

No electrical power

You must find the reason the main breaker is popping ...

I'd start by unplugging everything and remove all breakers. Turn the main on ... does it pop? If it pops here look between the breaker panel and the end of your cord. Turn the power off - reinstall the first breaker - turn power back on. What happens ... keep doing this until the main or individual breaker pops - investigate that circuit to find your short.

If you get all breakers back in with out popping anything ... start plugging stuff back in. Something is shorting somewhere.

Let me know what you find please.

thanks
