Say I have a large building with dimmable high bay lights installed, how can I automatically reduce the light output of the lights at certain times or if the lux falls to a certain threshold?

Neighbour is having a 300l Hot water tank installed in an outbuilding and wants the two immersion heating elements on two separate timers and both can be run independently or can be on at the same time. He likes everything tidy and instead of having two separate time clocks installed which he...

A mate of mine got a new garage fitted and he wanted a 32a socket fitted for his welder. Sent me a picture this morning that they didn’t fit a socket for the welder but they fitted this round pin socket instead apparently on the same 32a ring they installed. Can anyone enlighten me as to what...

Neighbour down the road milks cows. This past two mornings, an hour into milking, the cows started jumping to the roof like they were getting a large shock. It would happen every 10seconds etc in pulses like a cattle fencer/energiser. Would last for a minute or so but the farmer would open the...

I was told you can get a 12v non contact pen tester like one of those 230v non contact models electricians use. Is this true and if so, can anyone recommend one? Looking to test wiring for breaks in the cable in various vehicles like cars, machinery etc.

Looking to install some led high bay lights but not sure what brand or type to go for. These ‘UFO’ type lights seem to be very popular. Have any you guys had good reliability with a particular brand? Nothing worse sticking leds up and watching them fail in no time at all. I have seen luxum led...

I have a 16mm2 t&e feed going to an outbuilding which feeds an old MEM fuse cartridge CU. This is being ripped out as the building it covers is being tossed. Two new outbuildings are being built adjacent so I was planning to fit a new CU in each building splitting the 16mm2 supply to each CU...

Picked up a new Stihl TS420 14” Cut off saw but didn’t get a disc as I wanted to do some research first. Has anyone got any recommendations for a concrete disc? Seen a few Bosch discs but know very little about their quality.

Looking to replace a few cheap led floodlights which have started to fail. Thought it was great at the time buying them cheap so if they fail, it doesn’t cost much to replace. Cost soon adds up and some of them need a telehandler etc to get access to. Anyhow, a company called luxum led this...

Looking for recommendations for a rotary laser for work outside mostly. Not sure whether to pay extra for a green laser over a red one. Require it for putting up steel work for sheds and for laying out drain levels. I see there a lot of sub £300 lasers on eBay and amazon but I would rather...

I am installing a ptz camera for a guy and lucky enough, he has a socket a few feet away. I haven't checked yet but going by the use of 25mm conduit, I recon 4/6mm. I want to run a cable from this socket a few feet to an enclosure. I have only got 2.5mm & 16mm t&e. Can I use the 2.5mm if I...

Neighbour nearby has a bore well and it cutout during the night. Lack of air pressure in the pressure tank caused the pump to switch on and off too quickly and the 16a switch below isn't working. I tried a few local places for a replacement but can't source one and the nearest well pump...

There is a lot of talk these days when linking two buildings together underground using Cat5e/6 due to earthing differential between the two buildings from what I read and why Fiber is recommended. Does this earthing differential is a factor if the two buildings had separate electric supplies...

I am trying to fix a proximity reader for a business, one which you can walk through and the reader reads the code from the tag etc. The reader consists of a single core type cable aroud 6mm which forms a loop/ring from a control panel around the reader and back to the control panel. The...

Neighbour has two separate augers in his milking parlour and each are controlled by a timer relay switch that are set for 10-15 minutes. One auger is always having problems with the time switch and it has been replaced twice already and has failed again. Seems to last 3 months at most. The...

Spent yesterday installing a 70w Metal Halide outside which was an awkward installation. Anyhow, after all that work, the bloody thing switches on fine, but after 20 seconds or so, it goes out. If I go away can come back, it sometimes is back up running. If it does go out and I switch it...

I was at a house the other day and they showed me a newspaper which had a story about a Dairy farmer who went out to milk his cows one morning and found the cows in his shed all dead. It appears the previous nights lighning hit somewhere and the strike went down the automatic manure scrapper and...

I have a Riello Mectron 3bm burner/boiler outside and its controlled by an analogue time clock. I think its time I got a thermostat installed as its currently starting and stopping based on the water thermostat. I have been looking for a wireless thermostat but I don't know what works with an...

Just over a year ago I installed a number of High Frequency 58w Twin weatherproof fluorescents in one of my outbuildings. The lights have never been on this past few months due to the long evenings but this past few weeks, I have been switching them on. Every couple of days, there seems to be...

I have Hager CU in the garage and I am taking a supply to another building further on down the yard. I have 25mm 3-core swa buried underground. I am looking for suggestions as to a simple way of connecting the swa into the hager cu. Trying to bend the cores inside the cu for connection will...
