with having a number of 240v plug sockets we are going to be fitting a charger and when hucking upto shore power we want the charge to come on its own.

Jonny "Inca" has a Sterling charger fitted which like you say comes on as soon as the shoreline plug is inserted..

The female socket on your boat will need to be connected to a consumer unit the charger then being fed from one of the trips. I think my consumer unit only has 2 trips and a main one . The other one supplies the immersion heater in the calorifier. cheersbar

When you do get your electrics fitted Jonny you may find a blanking plate on your Calorifier that you can replace with an emersion heater element ( Not expensive either really) Then you get hot water while the mains is plugged in without running the engine cheersbar

Hi Jonny, if you're starting from scratch it is simpler to get an all in one marine unit, battery charger and 240v distribution all in one unit, saves time and needs a lot less seting up.

Hi David this is the way the previous owner had installed it

16amp socket mounted in the stern well from the a wire running into the rear cabin it has a 240v plug on the end. just below that a 240v plug socket which when plug in gives power to the other sockets onboard.

now the connection isn't a permanent connection in two pieces would it be best just sticking a consumer unit or fuse box there and connecting it up.

as i don't think there that expensive or am i wrong. it was just an idea of mine as to make Curlew a little bit safer incase or a short of something major whent wrong just to be on the safe side

Danny as you have had this done to Inca what was the cost if you don't mind me asking did you need to change or add a thermostat?

David any answer to my last post when to bed soon after as i was dropping off :shocked

I recently started the 240 on evenstar

you need a 240v inlet (female i.e. you cant see the pins) mine was £6 from go outdoors

coonect that with some 2.5 mm flex to a consumer unit mine was £24 from B&Q they usually come with just a master on/off switch so you will need a mcb (circuit breaker) rated at 13 amp for just normal electrics on the boat my unit is an MK make so the breaker was £8

you can hook up your battery charger direct to the mains (after the breaker) or fit a smaller (5amp) breaker just for the charger

note if you wire in your charger it must be a type which automatically shuts off when the battery is charged or you will damage the battery.

Jonny,

The unit on ebay does not contain an RCD, the bit that protects you from getting a fatal shock, it contains MCBs, these are resettable fuses effectively, but will only trip when the current rating has been exceeded. Electricty and humans do not mix, electricity in water based environments and humans even less so. I would strongly urge you to seek professional advice on checking your existing setup and any changes you plan on making.

Current government legislation now prohibits the home diyer from making changes to their own household electrics, beyond a simple change of faulty socket or light switch. Any additions and new installaions have to be performed by a suitably qualified person and certified. The BSS is sadly lacking on it's definitions and requirements for cabling onboard a boat.

As an example, you should consider the use of sacrificial anodes on the hull to protect any metals parts of the boat submersed in water. If the shorepower you plug into is not properly earthed and other boats around you have an earth leakage fault or faulty setup, by plugging into the same shorepower your boat may well provide the path to earth via your submersed metal parts, which will start to dissolve over a period of time. An anode is made of softer material and will dissolve before any important parts, rudder, prop etc. Anodes have to be the right type, depending on what type of metal they are meant to be protecting. They are a lot more important on metal hull boats, where the hull itself can be in danger, but even on grp boats they are important if your prop is directly connected to the engine and gearbox which will normally be earthed.

There are a lot of things to consider and for your own, and others safety, electricity is on area where you really need suitably qualified advice.

If you really want to continue down the diy route, then at least seriously consider David's suggestion of an all in one charger, rcd and consumer unit. Most of the things that can seriuosly go wrong in a diy setup will have been covered.

edit to add there has already been some potentially lethal advice given on this thread and advice that wouldn't stand up to scutiny in household wiring, let alone a boat setup. I am no expert on current legislation, but did do the 15th edition electrical regs, quite some years ago, but am not current on latest requirements.

I perchased a 240v auto shut off charger off ebay?

thats why i was asking about a consumer unit or fuse box for the charger and shore power.

Here's a link to the All in One 240v distribution combined battery charger

how much were those

Jonny,

I think it's fair to say that an all in one is going to be the more expensive route generally, although I don't know exact prices, but the far safer route for a diyer. If you are going down the route of separate components, then it will be cheaper, but you do need professional advice and installation.

They range from £220 for the 10a to just shy of £400 for the 40a Jonny, not cheap but not a lot more than a quality charger of the same rating, and as Keith has intimated, they are a sure safe route for the DIYer starting from scratch, they really are fit and forget.

for that price i think we will may just go with the consumer unit as the best option for us aswell as cost. but i think maybe looking into it a bit more tho cheers:wave

Please Jonny, humour me, don't use a consumer unit without residual current protection, I do not wish to appear melodramatic but I'm a bit busy to be attending funerals at the moment.

Hank, I think you will find you need a male inlet as the live power lead from the supply will have the femail plug on it so you cant touch the pins.

The boat inlet will be dead when its unplugged and exposed.

I stand corrected the pins should be visible on the inlet on the boat (male) as Pete says

While an RCD is very desirable it is not a must have. You must bear in mind that the shore power posts round the broads already have one built in. Obviously if you intend to regularly plug into a straight 240v supply then the RCD becomes more important (they cost £50 or so for MK)

As for doing your own electrics it should only be attempted if you are confident and competent with what you intend to do. As you are in effect only fitting a consumer unit and inlet this is quite within the abilities of the average DIY'er there are plenty of websites showing how to do it and if all else fails the consumer unit usually comes with pretty specific instructions. If you don't feel comfortable doing the job yourself then I'm sure if you buy the bits you must know a sparks who can wire up for you.

As for the charger while people are recommending £200+ units/chargers I for one can't afford that sort of money and am quite happy to fit a cheap & cheerful charger onto my new consumer unit once I have bought the appropriate RCD.

Hank,

RCDs like any other piece of kit can and do fail, therefore best to rely on the one in your boat with known history, than the shorepower post, that you hope has been tested regulerly!!! Incidently it is now illegal for the average DIYer to change their own consumer unit at home, whilst it may not be illegal for the aberage DIYer to fit their own consumer unit to a boat, I would strongly suggest professional help and advice.

I think I have said it as many times as I can, so shall leave it at that.

Hi Jonny, An element for your Calorifier will only cost about £25 So no big expense for the hot water side of your project cheersbar

Jim i think i would need paint by numbers to understand what to do

Please Jonny, humour me, don't use a consumer unit without residual current protection, I do not wish to appear melodramatic but I'm a bit busy to be attending funerals at the moment

Iam totally lost at this point i was hopeing for some simple advice for a simple minded person i dint go to NASA for an education you know :-D

I was hoping something simple to install not to costly and effective for what we need but it looks like at this rate we will keep it the way it is we will have to see

Jonny,

I'd say that if you're planning on keeping it the way it is, it might be worth buying a plug in RCD

whats one of these when its at home JZ?
