Although I agree with the comments made as to the omnitest and the like outfits etc who test for peanuts 50P an item in some cases, there is still an earning to be had if done right I charge £1.85 per item fixed or plug in I however repair/replace damages plugs,cords outlets etc where needed at...

When completeing a EIC on a TNS how is main earthing conductor recorded if it's SWA and how can I work out CSA Dev

as far as I understand it all joints etc must be accessable, right?, and there is no mention of the same being disallowed in lofts/attics/ if there is I cant find it, this is a remark made by a contractor, I alway when possible try to avoid any joins at all, but this guy brings every thing into...

Perhaps you can tell me am I wrong overcurrent is L_N fault in an ok circuit and a L_E is a fault to earth,and what then is a mccb or a mcb as I understand it a mcb is a generic term for a circuit breaker and a mccb is now been given over to mean a moulded case circuit breaker But again this...

Ok why have rcd at all, at present we must have efp and ocp on single phase why does the same not apply to 3 phase a 3 phase MCCB does not have efc prtotection, over load only, yes I know it amounts to the same thing (automatic disconnection) wether its a short circuit or a fault to earth We...

BSBS, they do not refer to those as (RCD's) rather adjustable thermal protection is this the same and can you tell me a make (not proteus) Dev

tri phase mccb's do not provide earth fault protection, as do rcbos' an rcd is required but where is it to be installed, at origin of supply apparantly not So if a tri phase is installed to prvide a supply to one three phase circuit where's the protection ?

How is earth fault protection provided on a three phase board, debate amonst subbies on site, no single phase circuits, and a 60973 main switch Dev

Pugwash cheers for that, gives me another avenue to explore, This things been out of commision for 3 years and each fault I clear somthing else pops up Ho Hum another day another challenge Dev

Sorry the 9k is total load if all are working together ie cavity and steam this will not happen as it's either or. the elements I am testing are the boiler elements 3 X750w 2.25 KW so I should get 9.8amps in and out but i get 5.6 L and 10 N I use a cheapo clamp it's generall good for guidance I...

It's single phase suppplying a combi oven, testing it at the terminal block inside the oven I have good access and the tails are on their own no other supply in the same area and the reading responds to the boiler elements cycling on and off, I have metered the elements and there is none down...

Hi All I have a current draw of 5.6 amps Line and 10.7 Neutral any ideas why I should have such a disparity. :( Devlin

you'v got to love our British "can do" attitude though. :D but pleas tell me the plug is'nt going to that socket !!

Coljack Hi spot on, you got me thinking I knew the motor connections were ok and I went along the phase feeds and checked them in and out of the contactor, overload device etc, and on the centre one the terminal screw was stripped tight enough to pass a cursory check but, I stripped it out and...

I have an phase current draw imbalance on a motor , rotation is ok and voltage on a;; three are good all the way down stream, at the motor connections I get 6,3.5,6 amps respectively can /would a contactor issue create this this is a new motor, Devlin

Sounds like the lad is doing a grand job under the circs and has enough balls to complete the job safely, if not technically brilliant and has shown enough inititive to get on with it and the sense to ask advice kinda like the young men we had in the air over the south coast 65 years ago and if...

I watched a CU install, one guy put the cpc ends in a driver and twisted them together then sleeve both together when I commented he grunted "its quicker" he had all the circuit conductors out the wall then offered up the cu popped the ends through and fitted the neutrals then the cpc's then...

I have never ever encountered a brick wall that is flat enough to screw a plastic or pvc box to the plastic will break and the pvc will distort given the the fact that engineered brick will destroy most diyer's masonary bits the tendancy therefore is to drill the mortar with the results I...

On a purely personal note I would have used metalclad, plastic pattreses usually break when you screw them to the brick and are a target for ladders bikes etc and the earth issue is resolved also Dev

Why bother for about 30 quids worth of 4mm and some double metalclads it stops being theoretical and becomes practicle, and for the picky I mean replace the whol dammned lot Dev
