Can Anyone Help?

Hi, I am having a bit of bother trying to find an mcb for my Abi Marauder caravan. It is a Hager 10 amp double pole mcb. As far as can make out, it is the double pole part of it, that I am having trouble with, there are plenty of single pole 10 amps out there. I was on e-bay, and I have seen a switch that looks identical, but it is a 16 amp. Does anyone know if I can fit it ? The seller has not replied to my queries yet, for some reason. Your help would be greatly appreciated. Thanks . Brian.

Hi Brian,

 

You can fit an MCB that has a higher amperage as this is the current carrying capacity of the unit, it will still trip the same in the event of a fault.

 

In deference to my more knowledgeable colleagues I must add that the MCB must not exceed the safe rating of the circuit it is intended to protect.

 

There are a couple of sparkys on the forum so I am sure they will be along to offer further guidance.

Nice to hear from you Steve, thanks for the advice. From the picture on e-bay,it looks identical, I just hope their is no variation in size. I will maybe wait a bit before commiting myself to buy it. Brian

Does it look like the original.

 

It may be worth posting up a picture, as it may be an isolator not a MBC, in which case a higher rated unit may not be an issue. Also if your van is not fitted with a RCD, then it would be worth fitting one in place of an isolator.

The amperage rating is to protect the capacity of the wiring so you certainly must NOT fit a higher rated MCB than is there now.

 

I'm not sure why your having trouble finding Hagar replacements, dual pole are now the norm and not the exception they once were.

 

My advice would be to try your local electrical wholesalers, remember though the letter after the amperage is equally important, probably a 10Amp 'B'

 

Most MCBs though of whichever make are of a standard size so should fit,

I am a qualified electrician and I can assure that Double Pole MCBs are NOT the norm when it comes to domestic installations.

I think you will find great difficulty in finding one in an electrical wholesaler, they are, however, the norm on touring caravans and most caravan dealers should have them in stock.

The standard modular width is 17. 5 mm and most will, in theory, fit in a caravan consumer unit if BOTH sides are connected by cable rather than bars.

If bars are used, it is quite possible that a different make will fit (in the normal domestic market several brands of MCB are "badged" variants of the same unit). You would need to make sure that the terminal size, type and position is suitable to connect the unit to the bar.

Could I ask why you need to replace the unit? An MCB will normally give years of service unless it's been repeatedly tripped by a recurring fault.

Thank for the advice,I will try a bit harder and look for a 10 amp that is suitable. The switch I have just packed in very suddenly. We where using the van when it happened. All of a sudden the sockets failed. At first I couldn't work out why the power failed,as the switch was still in the on position. A relative of the site warden turned up the next morning, looked at it and diagnosed the problem. There is power going in ok, but not going through the switch. Nothing extra had been switched on, a tv was on, that was it. Thanks again. Brian.

Thanks for your help, if I can match another make to mine safely, I will give that a try. I actualy saw the one you googled, and it is similar to mine, and yes it is an mcb.

chillypenguin's reply directed you to TLC, a really superb chain of electrical wholesalers. Take your old switch to them and ask their advice - they will probably test it for you. They have quite a lot of branches but if there isn't one near you I think you can email them.

I have been on to the Caravan Shop in Great Western Road,Glasgow. They have been waiting on them coming in,and they arrived today. It's not the same make, but I have been told it will fit ok. Fingers crossed. Brian.
