How much is a used coleman vertex 7500 portable generator.how can i know if its in g ood condition
Midwest USA... A working generator in good running condition should sell for around $0.05 a watt +-, so 7500x0.05= $375. Excellent condition add a penny. NOS add another penny.
A working generator in poor condition 3 cents/watt.
A generator that doesnt work, i.e. engine doesn't run or engine runs but no electrical power is $0 to $50. Repair costs of some generators cost more than a new one.
As for operational status, the typical shop vacuum makes a handy load tester. The shop vac load along with a "Kill A Watt" power monitor will provide an independent voltage and frequency analysis.
Be sure to plug the vacuum into every outlet and if any outlet doesn't work consider the unit non-working.

Siemens QF230A keeps tripping after installation.
So likely you have a 3 wire dryer cord and a 3 wire branch circuit. The dryer neutral is bonded to the dryer frame and the third wire of the dryer plug.
There were code exceptions for dryers and stoves that allowed timer motor circuits to use the neutral as a current carrier and frame ground.
To use the GFCI for the dryer you will be required to add an additional conductor (new 3 wire+ground cable) and separate the neutral to frame bond in the dryer and use a 4 wire dryer cord.
Likely you also have some GFCI single pole breakers and replaced ungrounded receptacles with grounded (another code exception) and they work OK. The dryer and stove are different as there is current on the third wire where as on the ungrounded receptacle GFCI there is no 3rd wire.
In breif, the neutral (current carrier conductor) from the dryer must be isolated from the dryer frame and dryer ground (fault current carrier conductor).
Or just leave it the way it was.
Check with local authority with jurisdiction for local code requirements.
