Did you have a survey when you bought the house? If so have a look and see what the surveyor said.

May be they belonged to a union?? :D

Table 10B and 10C of the OSG. Exposed 1mm/1.5mm earth cables aren't mechanically protected when they stick out of a JB. I wouldn't rip an installation apart to fix but if its something you have been doing I'd stop.

No, the exercise will do him good.

Some energy savers are not rated for continuous use so read the small print on the packaging before spalshing out.

At 40mm you are limited to a maximum unvented branch pipe of 3m. This is measured from the furthest trap.

Both. If you cannot access the switch: 1) it cannot be used as a form of isolation. (May have to turn the ring off to fit new filters/bulbs) 2) How would you change a blown fuse? You need to consider environmental conditions. Grease build up might increase the fire risk. Also bear...

I'd use an FCU and put it somewhere where it can be accessed. Don't hide it behind the appliance.

Basically you are testing to ensure the cables are not broken. By joining two of the cables together you can test from the other end by putting one probe on each cable. The three tests ensure that all combinations of wires are used. The isolation test then checks that none of the three...

1) You let a plumber use a hammer? 2) Check the wiring in the switch and ceiling rose. (RCD points in another direction) but check the black switch return isn’t run to the Neutral. (It should of course be marked by red sleeve or tape. 3) Use a multi-meter with the power off to check for...

Why do you need to know? Read any writing on the fuses. If they have two coloured dots on them then they are semi enclosed re-wirable fuses. Round pop out buttons will be plugin MCB's. Little switches will be DIN type MCB's. Read the text on them. B6 would be a 6A MCB on a "B"...

I always use the old kitchen units with kindling. :lol:

If its TT you must make sure the enclosure is insulated if it’s placed before the main RCD. Alternatively in a TT install you could put the DP RCD in place of the isolator. If the CU location will need meter tails over 2m you will need to install your own fuse to protect the tails. Again in...

To name three reasons off the top of my head : Fire prevention, mechanical damage protection and shock risks. Earths carry current (and hence have potential) under earth fault conditions.

I need to get a new circular saw has any one any views on the Makita – 5704, 5703 or Dewalt DW365? I willing to spent up to £150 for decent piece of 110v kit.

Hi Tom, I've seen it done this way too, but I'm not 100% sure what will be acceptable today. I was thinking of closing with polystyrene then mortaring over the gap. The window will sit slightly in front of the inner wall allowing me to fill the remaining gap with mortar. I’ll have a...

only if you have a fire extinguisher to hand.

Assuming the shower unit contans both the RCD and the shower circuits MCB you connect by splitting the meter tails. Search this forum for HENLY blocks. This is a job I would recommend is left to a pro. (they could also safety test the shower installation, bonding etc.)

Whatever happend to old fashioned live working??

Two time saving tips:- Before you remove the light switch note where the wires go. Check you have an earth (which is connected) before you buy a metal face plated dimmer.
