I have an old rewirable fuse type comsumer unit that i would like to
Is this expensive?
Have been told that to replace my rewirable fuse system with circuit
MCB's is a really easy job and that i could do it
Are you perchance in the UK? I've seen rewirable fuses in use over there.
I've heard about rewirable fuse panels being used in homes in the USA,
but in some 50 years of fooling around with stuff, I've never actually
seen any in use, just some old photos of them.
I have seen cartridge fuses with replaceable links, but these were for
"industrial strength" applications.
In any case, replacing a fuse box with a breaker panel isn't exactly
rocket science, providing the existing wiring insulation is in good
shape and doesn't start falling apart when you have to bend and twist
wires to get them out of the old box and into the new. The challenges
are likely to be more mechanical that electrical, i.e. will all the
existing wires be long enough to get to where they have to when you
change boxes, and if not, how best to rectify that situation.
Depending on where you are, codes and inspection requirement may be
factors limiting your being able to legally do the job yourself. Don't
approach this project blindly. If you were experienced you wouldn't be
asking the question here, so get someone who knows what he's about to to
look over your shoulder.
Only a few people are born into the world knowing it all or thinking they
know it all. We learn by asking and by doing. Have you never asked how to do
something or do you hire everything out rather than ask questions?
I have to agree with the other two posters, if you have to ask then you
might be better off getting someone with experience to do the job for
I'd also add that if you change panels you also need to bring the new
panel up to current electrical codes. I changed my own panel and had to
bring grounding up to current code. The old panel used on the nearest
cold water pipe for a ground and didn't jumper across the meter. I had
to run a ground wire to the pipe where it entered the house, add the
jumper around the meter, and add an 8 foot ground rod outside to meet
Once done you will also need to have your work inspected. Before
starting any work check with your local codes enforcement office. In
some areas you may have to have a licensed electrician to do the work.
Nothing wrong with DIY. Read, ask, learn. If it's wrong the inspector will
tell you what must be corrected. When the inspector approves the job, you'll
have the satisfaction of knowing you did the job right. Many times the pro's
don't bother with permits and many times the job isn't done correctly.
Depends who you hire. A licensed electrician isn't necessarily an automatic
pro job. Sometimes it is. Hiring a contractor is like playing the roulette
tables in Vegas.
