Wiring in 2000w inverter

OK, but you won't be running a microwave if you are only drawing 700W. Even my old 600w rated microwave draws about 1300w when in use.

A 2KW inverter is fine, and will run high power items like kettles, microwaves, toasters with no problem as these items are usually run for short length of time. If, however, you ran your microwave for 20 minutes, you would really need a large domestic battery bank to run it from.
 
Wasn't a case of working out how it worked, it was an investigation into an unknown inverter and a question as to whether it was centre tapped or not.

That type of inverter that the OP has would be potentially lethal if used in such a way as you mention.

Rather than the usual snide comments, perhaps you'd care to explain ?

Try better than the last time, when you posted the comedy you tube video, where you couldn't work out how the inverter worked :):):):):):)

It was a Durite inverter that the boatyard you work for had in stock, pretty standard fare. It was nothing to do with being centre tapped or not, you claimed it was but then others pointed out it wasn't. You were attempting to demonstrate how to wire it so the RCD would trip, but couldn't figure it out. Someone will probably post a link to it :)

Explain how this will happen then ?

Still waiting for you to explain how you would wire it.

Well to keep this simple I will not be using the inverter to power more than 1 or 2 relatively low load items at a time, or 1 larger draw item and that is why I have fitted dedicated sockets and wiring for them, as if I need to run anything big I can always run my 4Kw generator.

This inverter is purely to retain a modicum of respect for others when we are at anchor and want to run the ice maker etc
 
Got me scared as I have a floating 1000w inverter with my computer and screen on it
I was always under the impression and It depends on the Inverter but mine has said this so no stress
I suppose you need to really read what your inverter does

RINVPR2000
Professional 1000W pure sine wave inverter, suitable for 12V vehicles, with integral Residual Current Device (RCD). This can replace the need for an external RCD and will switch off the inverter in the event a fault is detected between live and earth. This protects the user against electric shocks.

Sounds like a good design, mine doesn't have the integral rcd.

This is also for the "conversation" above..
Imagine that mains 240V is passed through an isolating transformer. A Live - Earth fault will not trip a RCD no matter where it is in the circuit. The transformer output will be floating and the Live will float to Earth, no current will flow to Earth so the RCD will not see any residual current and will not trip.
For a RCD to work the supply (output from a transformer or stand alone inverter or generator) must be tied in some way to Earth. The 2 popular ways are Neutral - Earth bond or centre tap.

For the RCD in your inverter, Flying Goose, the inverter must have an Earth connection, it may well get this from the 12V input (almost certainly it expects vehicle chassis to be either battery + or -, both work fine.)
 
I have an inverter the same as the OP. The output of mine and OP's inverter has a UK power outlet.

What I did we to connect the wires fron the RCD line ans neutral and the earth which connected to a UK mains plug that has the earth connected to the neutral giving a return path so that could be a difference in the line and neutral so the RCD would trip

Can you explain this a bit better for me please?

Wire a 13A plug with Neutral and Earth connected. At the other end of the cable connect Live and Neutral to the input to a RCD. Wire your inverter fed sockets to the RCD output and the Earth from the first plug.
This will allow the RCD to trip. However it wont provide quite the protection you would hope for. It will trip if there is a Live to wired Earth fault, it will trip if there is a Neutral to wired Earth fault IF any equipment fed from the inverter socket is drawing power. It will NOT trip on any fault where Live or Neutral connect to other metalwork not connected to the wired Earth. (depends on inverter wiring, so not generally reliable)
It will most likely trip if there are 2 faults, you touching something and getting a belt is often the second fault. A properly installed RCD will trip before you get to be the second fault.
