lectrician we had to do the same

Yes i would expect that you have amain in and a main on and there fore only switched live and neutral at the lights with the second light wired from the first.

I have looked at the solution you posted ijsalter , with regards it i have taken it that you have a main in and a main on, if you only have one cable at each light then felix has the right solution ie you have only a main in. If you have 2 cables to one light in the hall, and one at the last...

Yes :lol:

The 3 core&earth cable to the outside light ,this has probably been put in so that a security light with a PIR sensor could be fitted and an override switch used so that you could turn the light on if needed with out having to activate the sensor all the time . ie red=permanent live...

Bond the length to the shower ,to the shower cable earth with 4.0mm eath cable and clamp. Then at each joint cross bond the pipes across the joint using 4.0 mm earth cable and clamps,this should maintain the earth continuity of the copper pipe .Under the bath cross bond all copper pipes and the...

The iee on-site guide refers to 6.0mm as having a cpc of 2.5,this is on page 45 (conventional circuits). In 18 years i have not come accross new 6.0mm with 4.0mmcpc .

Fwl i think it is you who should learn to use the regs book perforated cable tray is method11, method 1 as i said earlier is clipped direct. regarding 6.0mm with 2.5 earth you say 4.0mm read your on sitre guide as well this referers to conventional circuits where they give phase as 6.0mm with...

See reference method 1 clipped direct 6.0mm=47amps. Old (2.5mm) is 7strands referred to as 7029. 6.0mm has 2.5mm earth core Dam, we have already establish that the cable is 2.5mm NOT 6mm. No you assumed. He has already stated that he used cooker sized cable in his replacement. This i...

Can you tell us if there were any links between the switches on the 2gang switch ? If there were not try removing red3 from the wall light switch(left) and placing this in the com of the ceiling swith (right)move the black 4 to the l2. In the single 2 way switch move the red by itself to com...

If it is just the henry tripping the circuit check that the plug dose not have the neutral connected to the earth pin,have come across this with diy people connecting plugs before(the old saying well it worked before you rewired and put these fancy trips in).

You don't need the power on ,i presume you checked all the mcbs/fuses. Depending on the size of storage heater you should be able to tell how many elements are working by turning off the d.p sw ,removing the cover of the storage heater and measuring the resistance of the heater at the terminals...

Most mcbs will take 1.5 times rated current for a period of time before tripping ,this is done thermally within the mcb how ever the mcbs are designed with this in mind so it cannot be overloaded to the point of damaging the installation . In my view of this in the domestic setting ,cookers...

I have a range cooker rated 15.6kw i wired it in 10mm t&e cable, via 45d.p switch. When i installed it i put it on a b32amp mk mcb with the possibility of uprating this if i had any problems, i have yet to change this in 4years ,the only time it has tripped is when an oven element blew short...

The cable you describe is mineral cable,these types of cables need special tools to strip and make the end gland off ,they then need to be tested to find polarity,insulation resistance etc. If this cable end is damaged you will need a sparks to remake the end of the cable, however i would...

With regards to mapj1 earth in a pre rcd tt installation the regs do support this read bs7671 reg 531-04-01 in conjunction with reg 413-03-09

Do you have 2 electric meters if so you probably have an off peak installation . The time switch then just controls your storage heating board,in the older installs the time switch sometimes had a boost period in the day, (to top up the old type of storage heaters as they were very poor at...

What is the likely load in the shed ? How far is the shed from the house? Is the supply underground? These questions need to be answered to be able to determine the size /type of cable to be used before you decide what fuse/mcb size to use.

What is your supply? check in the reference section at top of posts. If it is TT you would need 2 Rcds 1, 100ma time delay and a 30mamp for your sockets ,etc

In the first instance yes you need to put the rings on the side of the rcd. This is for added safety,and a must if any outside equipment can be plugged into any of the sockets,ie lawn mower etc. What type of supply do you have, (look in the reference section at the top of the posts)? What...
