Blown light bulb trips out all of the house lights

Submitted by on

When a halogen bulb blows in either the bathroom or living room it blows the main fuse and we lose all of the house lights?  Anybody any idea why?
The light fittings are multi lamp - and not overloaded.

Hi AngiDD,
There are a number of reasons this could be happening, from an over sensitive mcb in your consumer unit (fuse board) to inferior lamps. 
To this end it will be difficult to get to the bottom of the issue without an electrician actually visiting your property to carry out some tests.
I know this is not what you want to hear but with issues like this it is always best to have a professional electrician check things out for you.
If you do not have or know an electrician you can of course find your local electrician in the My Local Electrician directory here
Hope you get to the bottom of the issue and please do let us know how you get on.

Hi Angi,
It is often the case when we visit job that report this as a fault that we find, lamps (Bulbs) have been purchased in the supermarkets or the Big DIY chains or even worse the low end DIY outlets or Pound shops (Trying desperately not to mention names).
May of these lamps are manufactured to a very low standard and when they blow as lamps do, then the components do not separate quick enough, causing the MCB to see it as a fault.
My advice would be in the first place, check that you are not using cheap lamps, if you are then replace them with good quality brand name ones purchased from an electrical wholesaler rather than a DIY shed.
You suggest that the lamps in question are Halogen and it is often tempting to go with the cheap offer packs like “three for a pound” or something like that, the truth is this is a false economy not every lamp is manufactured to the same quality, however for a Good Halogen GU10 you should expect to pay between £2.50 and £3.00 for the lamp.
Another option assuming they are GU10, is to spend a little more and get LED replacements, more expensive but in the long run a great saving.
