Sockets

trevskoda said:
As I said some inverters are ok and will not shock, others must have a neutral or eth connection, all depends on the make and design, mine has a earth point and is connected to the chassis which will run through the carbon tyres, esp if the ground is wet, I have tested and alls well.
Some others require a earth plate or spike, many older units work like this.

How do you test to make sure all is well please?

Mins testing plug. on very dry days I would still use a spike or mat wetted, to be sure to be sure. 😂

Trevor, the voltage alternates on an inverter. You don’t have a live and neutral, they are both live. Though not at the same moment. If you ground the so called neutral, you must have a rcd circuit after to offer some protection.

Wrong from what i read, only one side hot, other is ground, also best to run through the RCD unit rather than just an extension lead, your call.

I've got a basic socket tester, I'll try that when I'm all set up. I'll also have an RCD socket on the end of my cable from the inverter. So I assume if my socket tester shows the correct sequence of lights when plugged into my inverter outlet when it's switched on all is well? Crikey, didn't think it was going to be this complicated just to run a fridge for a few days!😁

Don't blame me if your eyes light up one day Trevor, getting it wrong can be shocking! Seriously read up on basic AC theory.

Ac is only live on one wire, the other is dead or earth, hence you will see a sign on units with one wavey line and one straight.
3 phase works like this for homes from the transformer with ground as neg, take a bulb at home and wire one side pos and other to a earth point and it will work.
 
rcds work by switching off if the two live ( or live an neutral) wires arnt carrying the same current

your bulb will just trip the rcd , they compare the current in the two live wires, or live an neutral, if its not balanced they trip. probably better to ensure theres always a rcd on the inverter output rather than maybe , sometimes, when you remember , can be bothered to using an earth spike or plate. same with generators.

Yes i have one socket on an inverter to power a 400w blow heater, time I fitted a rcd socket as some ne else may plug something else in, better safe than sorry
 
I have two ring mains ,one set of sockets fed from inverter the other from ehu. Simplest way I thought, but still suffer from hair dryer confusion 😕

. I only really want a double socket. One side for the fridge to be plugged in when wild camping, and the other in case my wife wants to plug in a hair dryer,

Have you worked out how long your battery set up will supply the fridge & dryer.

A 3kw dryer alone will draw around (3000 / 12) x 1.1 amps = 55 amps from the battery. This will flatten 100ah battery in under an hour.

Do the sums before nything else.
 
Watching that it says RCD wont work with a inverter, learn something new every day, folks please disregard all the crap I have put on. 😂 (y)
