Yeah, once he said he had an LNC2 with a forward CG problem I knew something was fishy.

Hi Tim:

 

If the inverter is really delivering 1100 watts to the oven then it is drawing 85 amps or so from your 14 volt system (over 100 amps if the voltage falls to 11 volts). Suggest you check carefully if the wiring/breaker and engine monitor are both up to that current delivery. You will obviously run the battery down fairly quickly even if the alternator will support 60 amps continuous.

Instead of adding useless lead in the tail cone, I decided to cure a fwd. CG problem with the installation of a more useful microwave oven in the luggage compartment. The CG problem is somewhat fixed now, but I seem to have traded it for an electrical problem.

I found a relatively small portable micro wave on the internet and made a fixed installation for it. It is a 230v unit, but I have just added a 14v to 230v inverter, which seems to work just fine. At first everything worked flawlessly, but recently the alternator breaker has started popping ever more often and is seems related to use of the oven.

If I heat something small, like a single corn dog, there is no problem but if I heat larger objects like a turkey leg, the engine monitor cuts out in an alternating pattern for a while and then the alternator breaker pops. But, then again, maybe that is due to the higher wattage needed???

I am afraid my 60 amp alternator is not quite up to the job or should I just install a heavier circuit breaker? The oven is labelled "CE 230v 1080w".
