Some have had the end fittings that hold the diffuses on drilled for conduit fittings or...

Hi Guys, I've been asked to look at a solution in a school where they're amalgamating their library and ICT room. They want to put a table in the middle of the library with 6 pc's on and I need to figure out how to get power there. I could cut out the concrete floor and put some floor...

Been asked to do a PIR on a school that i've previously done a bit of installation work for. Most of it is fairly straightforward but i have a few concerns regarding sensitive equipment etc.. They have fire detection alarm, intruder alarm, separate alarm for ICT suite and a smoke cloak device...

I have to replace some fluorescent fittings in a hall. The ceiling looks like it was built around the fittings so when the old ones come down, there will be an approx 4

Have to do a PIR on our school pool and have a question on the earthing. The plant/changing rooms were rebuilt last year by the council, they recommissioned all the electrics but the feed is from a PME system and they exported the earth. I am going to put in a rod but should the exported earth...

Are there any special requirements for test & inspect on static caravans? I just bought one and, as we're renting it out part of the year, it needs an annual PIR. It's included with the first year but, come next year i might do it myself and see if i can drum up some business doing some...

For a ring circuit, what is the correct way of testing R1+R2, or R2 alone, in metal conduit if the conduit is being used as cpc? ?:|

I have a Di-log 9083p and it's giving some quite sporadic readings with Zs tests. I do maintenance within a school so i am based in the same building, each time i carry out a modification i do a Ze at the main incomer and it does vary a bit but i was changing a board last week and, just out of...

Recently had some smartboards, projectors and audio systems installed. There is a low level buzz coming from the speaker systems which is tolerable but when a laptop is plugged in and powered from the mains, the noise increases 2 or 3 fold. If the power supply to the laptop is disconnected, the...

We have an outdoor pool at the school where i work and i've started preparing it for May, when it opens. Stuck the pump on Tuesday morning to begin circulating the water, came in yesterday and pump wasn't running. Breakers all ok so I assume the contactor was the cause (i suspect some leaves...

Does anyone actually use the 'by enquiry' method for finding Ze of Ipf? If so, who do you talk to?? I have tried to obtain the value for a property to compare it to my measured values and keep getting sent round in circles from the DNO to the supplier and they tell me that neither hold values...

been to look at a board change today, it's an old board with rewireable fuses, tn-s system. There is a clamp around the sheath of the supply cable with a 4mm earth cable running up to the earth block in the current board, i assume this cable needs upgrading (tails are 16mm, so i assume the...

I've got a box full of old crabtree c50's in varying ratings, probably around 50 single phase and a handful of 3ph plus a couple of main switches. What do you reckon..... worth anything to anyone or just bin them? Hate to throw stuff out but are they any use now?

I'm thinking of getting into fire alarms (installation and testing), i've only recently qualified about 6 months ago and am looking to add as much diversity to my work as possible. I understand there are regs, i have BS5839-1 and i know there are others i'll probably need in order to ensure...

I'm replacing a series of distribution boards in a school, it's being done a bit at a time due to accessability and time constraints. I've replaced a board today, taken out an old metal crabtree board with c50's in and replaced with an MEM split load (metal again). All the cabling is either...
