electrical term?

30/pole...does that equal 30 amps per line..thats the way I read it..Rite or Wrong..?

Robert,

I'd need more context to answer this definitively.  Is this a rating marked on a switch or breaker?  If so, what other markings are there?

Offhand, I would say your guess is correct, but guessing is not indicated where safety is involved.

its on a power trans ferr switch I've had on shelf for 5 years (new) no instructions..It has line 1  and line 2 marked also common and ground..apears to have #10 wire in system and marked .o25 sec  delay..not there now to get more info...has relays for shore power-generator-inverter..haven't used one yet but will this time..if it is 30 amps per pole it should support 50 amp shore cord my 7.5 gen set or the two 3000 watt inverters..rite?might be incorrect on delay but was less than 1 sec..info inside cover on unit..

Yes, I would say it would be rated at 30 amps per pole.  I am assuming this is a two-pole switch, and not three, correct?

#10 wire is also good for 30 amps.

...if it is 30 amps per pole it should support 50 amp shore cord

No, a 30-amp switch will support at most a 30-amp shore cord.  Sorry.  You will need a 50-amp per pole, three-pole switch for a 50-amp shore service, and there the proper size wire is #6.

my 7.5 gen set or the two 3000 watt inverters..rite?

If it is a two-pole switch, that would be usable only for single-phase, 3-wire, 120-volt service, and a 7,500-watt generator is capable of producing 60 amps of that kind of power.  So, again, the switch is not adequate.  However, if your generator is instead wired for 120/240 split phase, 4-wire, then it should have a two-pole, 30-amp breaker, and this switch could be used to transfer half of that power, unless it is a three-pole switch, in which case it can carry both legs.  But you would still have the 30-amp limit on the shore power.  You could do this safely by terminating the shore cord in a breaker panel, then feeding the transfer switch from that panel with a 30-amp breaker; you could connect other loads directly to the shore panel (but then will only be energized on shore power).

A 3,000-watt inverter can produce 25 amps (continuous -- surge rating may be higher).  So, again, if this is a two-pole switch, it could be used with at most one of your two inverters.  If it is a three-pole switch, you can use both inverters so long as each is connected to a different pole.

HTH,

have in front of me:Model TS30 Power Switch         Maximun service     120V 60 Hz 1 phase         30 A/pole  2 pole        Time delay 20-30 seconds    I made error on memory for time delay gen set has 2 ea 25 amp breakers

OK, what you have is a 30-amp, two-pole transfer switch, which is suitable for rigs that use a 30-amp, three-wire, 120-volt single-phase shore service and a maximum 3,600-watt generator with three-wire, 30-amp, single-phase output.

For your application, you really need a 50-amp, three-pole transfer switch, since you have a 50-amp, four-wire shore service and also a four-wire generator set.

You MUST switch both hot legs PLUS the neutral wire when transferring between shore and generator, which requires at least three poles.  So even if you were willing to forego 40% of your shore input by de-rating the shore down to 30 amps per side (using an intermediate panel as I suggested earlier), this switch is still short one pole to do the job.

I am sorry to say that there is no way to make this switch work in your application.

  If you want to do a little converting I have some three pole contactors that you can have (some may even have interlock linkages ) ,can you  tell what the coil voltage is ?  call or stop by.

will do Dwayne...thanks for answer Sean...mlh1936 visiting 16th Dwayne if you intrested.will call.Any body need a ts30 power switch?
