Help with mains electrics please... (1 Viewer)

[Just smiffy]

hymer b544 2012, plugged in on mains from the house and all’s good when sharp puts kettle on when a fan heater is on and blows something..? Mains still works coming into the van and and everything works, charging batts etc... except mains plugs.... all plugs work if the inverter is turned on..? Checked all breakers and all good so a fuse has obviously gone somewhere but where.... any ideas..?

Thanks for the incoming....

Normally I would say 13a ring in your van on a separate trip on your main RCD box but you've checked that ,can't see it being on a separate circuit ,but I sit to be corrected .
Hope you sort it

I dont think you will have a fuse as such on the mains side it will be a trip of some sort.

We had a similar issue which turned out to be the small plug and socket that one of the socket circuits was running from, this was housed inside the CBE box with the RCD and circuit breakers in.

It turned out that some "pillock" had changed the wiring when fitting the inverter and they had put male pins into the plug and the socket so they didn't mate too well.

I found this because the plug/socket had gone brown.

RCD box, breakers didn’t trip so something has gone elsewhere.....

But they all work when the inverter is on, all the other mains stuff is working ie, charging the batts.... and my control board indicates that the electric is on..?

Standard Hymer wiring is an RCD feeding a 10 Amp MCB, I assume you have had an inverter fitted with a change over relay. Sounds like the relay has failed. I have a similar setup in my van this is how mine is wired:-

And where am I likely to find that Lenny, I believe @eddievanbitz fiited it, it’s a 1500 Waco? Inverter does it mean I’ll have to buy a new relay...?

Does your control panel have an input current (Amps) limiter that's set too low? Ours isn't a Hymer but it has that feature. Could be something else of course, but no harm checking.

Sorry not got a clue could be anywhere. The fault sounds a bit odd as I wouldn't expect a duff kettle to cause the relay to fail.
Have you looked at your incoming consumer unit to see if it has 2 MCB's one feeding fridge & the charger and another one feeding the sockets, it's not the normal way Hymer do it but Eddie could have added another breaker to make wiring a changerover relay easier. The fan heater & kettle will overload a 10 amp MCB.

I’ve had a look everywhere that I know where some wiring is (except I’ve never ever found where my victorn controller is?) and I can’t see anything wrong....

we are pluged into the mains on a relatives drive, the inverter was not on, we had a small fan heater on and the kettle was turned on and it obviously blew something as the heater stopped working and the kettle, everything else works on the mains as it should and the inverter operates the mains plugs as usual.

It’s just the mains plug that doesn’t work, it never tripped the RCD, I’ve tested it by pushing the test button in and it works as it should.... I’m now stumped ....

Have you checked the wiring connections for the 240v loop? it sounds like a wire come loose somewhere on the back of the RCDs

 

[Lenny HB]

Yep, thatsthe standard arragement, If you had a 2kw kettle and a 2kw fire I would have expected the 10 MCB to trip.
I take it you have auto switch over similar to what I have done for the sockets and the sockets are connected to the inverter and switch over when you plug the mains in. Somewhere the circuit will have been split to wire this function in. All you can do is have all the floor hatches up and follow the wiring. Could be something simple like one of the wago connectors coming unplugged.

 

[funflair]

You haven't tripped the relatives supply have you and then your Victron kicked in to make up the loss.

Sorted it.... by absolute chance and luck.....

I took the inverter out to have a look around the batteries but I’ve been around there before and already knew there was nothing but last place to look, I unscrewed the inverter from its mounting and as lifting it out I felt my finger push something, I had a look and it said fuse but no way of unscrewing it and realised it must be be a push in reset.... tried the plugs and it works...! Yay...

Thanks everyone for your quick responses as usual

Are you trying to confuse us? You said you had a Waco Inverter, Martin says its a Victron and it looks like a Victron to me.
Now if you had told the truth we could have sorted it out ages ago as the Victron has a bypass for the fridge & charger no separate relay needed.

I said I had a waeco inverter and have never seen my victron solar controllers I assume they are behind some panelling as I have 300watts up top, but I do have one of those little victron monitor thingys....

Sorry I said Victron for no reason other than he mentioned Eddie VB 2x2=5

I believe it is Waeco as its darker blue.

[Lenny HB]

I thought Waco ones were silver with black ends. All rather confusing really.

 

[Just smiffy]

Ok.... I have one of these...

[Lenny HB]

Even more confused now, looks nothing like your earlier pic.

 

[funflair]

I thought it was this one,

But now I think its just the packaging thats blue.

2x2=?

Try the overload reset button on the end of the inverter

Your about 10hrs late to the party on that one Eddie......
