F28 switch question

[larryeddington]

The below switch, control is mounted in my 120 volt panel, below it is controls for Genny which works fine as does shore power. to its right is the usual breaker box. I have not traced wires from this thing as yet, volt meter shows no voltage present. The boat has two resistance heaters inside cabin area. Possible it went to them. It is a switch and fuse box. Any ideas on what this is or was for. It has 15 amp fuses but is rated 30 amps. I do not think it is active anymore and want to remove.

Has nobody every seen one of these before?

For a inverter ? IMO its not OEM Trojan , as its fuses not breakers and a wire nut . Do you have twin 30 amp ? Just from looking at it , It looks to be wired backwards ( note the jumper wire on the fuse side . )

[larryeddington]

One wire nut bad, two looks like the fuses are wired in series, which is still 15 amp. I have some exploring to do, I have found a yellow wire and plug hidden away under gunnel just aft of the shore power entrance. It does not go to anything. I thought maybe at one time some PO was using a small genny somehow. However I think once I track it down I will find old not used equipment. I need to get the mode number from it and call GE and see what the heck it is. Obviously it is a fused disconnect of some kind. I am not sure it is a marine switch. I will let everyone know once I solve it. Just thought someone had seen something like it. In any case I do not like this old technology. I do suspect on a hunch it has something to do with the two heat strip cabin heaters though.

Nope just 120 from shore or Genny.

Thanks

That there is an indoor type fuse type safety breaker---- in my opinion I don't believe anything like that would be marine use as it would not be explosion proof with the sliding knife edges---- please say you won't try to use that----- you can still buy them new--- Mike

I don't think the fuses are in series , looks like the power is coming in from the right (fuse) side ( one power feed to both sides) and leaving on the switch side . I believe that to be backwards . If you have strip heaters that are not OEM then this could be the switched fuse box for them .


edit .

Just noticed , The wire , its not marine . Its the stuff you would wire you house with .

[larryeddington]

I was pretty sure it was not marine, as I said earlier cannot detect power to it under any conditions. Just wondering and I do not plan to use it. It is someone's crap work.

I was at the f28 today and tracked down what the above switch does. Apparently it may be obsolete as it is a GE cat # TPF230 and is called a Safety Switch. In other words it is a fused disconnect and does not appear to be marine. I went to the male plug that was hidden under the gunnel, plugged power onto it and the heaters now function. Took the switch out as there is a better way to do this thing through the breaker panel itself or using a sub panel or just replacing the whole breaker box as it appears to be a regular Murray breaker box using Murray Arrow Hart Breakers available most places. The Murray box appears to have been installed by Trojan and they fabricated a black plastic cover indicating it is the Trojan Sentry. Does anyone know where to get the polarity checking light?
