Need to buy some bricks for a garage. Approx. 3m by 5m and standard height with apex roof. Can anyone suggest how much i should expect to pay for the brick? And ways of getting the brick at the right price? thanks ______________________ moderator please note 9

thanks guys, But ive been told its good practice to run a 10mm earth to the boiler pipework if it is located outside the house, for example, in a small boiler house. Is this incorrect? And will 4mm cross bonding the boiler pipework do for the attached garage? thanks

Is the attached garage of a dwelling within the equipotential zone? The garage holds the boiler and associated pipework. Obviously the boiler will require a supply. But i was wondering if a 10mm earth is required out to the pipework? thanks

yes Ban i probably have upset him at some stage... Anyway, i thought he may have thought of Volt Drop, but the cable is 1.0mm. Lectrican, whats with the relays?

thanks and guys, yes i am surprised about the current carrying capacity of 1.5! Also, this business with the socket and the cooker. Should this double socket be protected by an RCD and if so will this be affected by nuisnace tripping from the cooker? Or is it enough to label the socket...

Checking a house and found 1. Immersion wired in 1.5 mm and protected by a 15A rewireable. 2. Double socket spurred off a cooker switch in the kitchen. Has anyone any solutions? Does the immersion need rewired or a smaller fuse installed and is this likely to trip? thanks as always.

thanks Plug... an acquaintance suggested a transformer with a higher voltage, but surely a tx with a higher current rating is required?

Fault finding on a bell circuit... Three bells are installed on a circuit along with a push and a transformer. When 2 bells are connected the push will ring the connected bells. However when 3 bells are connected they will not ring. I think each bell is rated at 0.5 A. However the transformer is...

thanks for your patience Lec... Seen this many times. Im assuming for local isolation (although the neutral wont be switched)

There is a supply from the t/clock to a 2 gang switch. 1 switch controls the pump and the other the burner. A 3 core flex goes to each. Surely then there is no permanent feed at these points, only a swiched feed from the t/clock? thanks for the info so far...

thanks guys, Lectrician - Is the constant live not at the timeclock? So there would only be a switched live running through from the house to the boiler/pump? [why not just use an s plan + if the boiler live is fed from two different places surely once it fires both lines will be live...

Plug, the CH is controlled via a timeclock fed from in the house. so timeclock OFF, no supply to the boiler. Therefore to turn the supply on in the garage without turning the timeclock on in the house 2 supplys are needed... thanks

A chap has a garage which is being converted into an office. Standard set-up of boiler in garage and central heating controls in the house (timeclock). At the boiler he has a 'house pump' and 'boiler' switch and also a separate 'garage pump' for the rad in the garage. The idea being to run the...

just an update... went ahead with the install. The pump had a load of approx. 1.5A. It is located about 50m from the house and overflow is not an issue. I was concerned about nuisance tripping and decided the 100ma trip would suffice. Althought this does protect the whole house and is not...

thanks fwl and plug, for convenience and due to the layout of the house and out buildings the supply will be from a f/spur of a double socket outlet. This will be protected by a HRC fuse. FWL - i would be interested to know about your audible warning system...

thanks guys, Reading John Whitfields Electricans Guide "Garden lighting, pond pumps and so on should preferably be Class 3. Where 240V equipment must be used, it should be Class 2... If accessible Class 1 equipment is used its supply system must allow disconnection within 0.4 secs.... Then...

gents. anyone any experience of installing a pump in a garden for a sceptic tank. What size is the pump likely to be and is RCD protection necesssary? cheers

thanks guys. the plan is to disconnect and relocate the pc points. as suggested the customer will remove the necessary points from the patch panel. Each pc point needs diconnected and removed and then refiited. Each point may also nedd extending. I am concerned as it is something that i have...

so the end at the panel needs to be disconnected then? And label the end at the socket and recoonect? And what happens if the end at the panel is not removed? cheers

i am removing a counter in a shop. There are various compuetr points linked back to a main panel. I have never removed pc points before and was wondering if there are problems associated with doing so? cheers
