Hi everyone.
I should start by saying I'm not sure I'm in the right place here (this isn't a householder issue - I'm making a Ghostbusters backpack for my son!), and that I have no knowledge at all of electrical circuits.
I have a simple circuit with 3aaa batteries powering a string of static...
Commissioning a busduct. My contractor has installed a 2000amp aluminum Busduct in a 17 floor office tower.

Had a call from a local caravan site… under new ownership, and creating some new pitches.
Went to site to have a chat, the guy already knew I’ve had experience around caravans.
He mentioned connecting up new units, general repairs, whatever… and he said they used “armoured” cable. 32A supply...
Hey.
I have seen those experiments with rubbing a baloon and creating static electricity to make a fluorescent light bulb glow. Im interested in making a similar experiment but with (gas free) electrical components.
According my research static build up electricity is high voltage low current...
Hi all,
Please take a look at the video. I recently have a arcade machine, but it is cause a buzzing/static sound. Can someone help me identify what is wrong with it?
I have a holiday caravan which I upgraded to a residential standard lodge. The old static had a 16 Amp supply which was OK as the oven and hob were gas though the supply would still trip if the kettle was on with the microwave but no big deal. The park owner upgraded the cable from the meter and...
Hi, currently we have a static caravan with a generator running electric to the caravan. We also have a boiler which lately have been having alot of problems with. Had plumbers out etc but still cuts out. I have an earth stake in the ground with 10mm earth to caravan fuseboard. Testing at the...
Hi I have a property and the mains supply is a TT system I need to put a temporary static caravan in the garden. The caravan will have a water supply to it and the cooker is gas. The caravan has its own CU rated at 40A with a 32A RCD. The distance is about 100m. My question is do I need a earth...
Hi guys,
Have a job on next week for a friend, my usual industry is maintenance so want to be sure I am checking all the boxes here.
He intially measured the run out at 122m, which would require a 70mm cable due to volt drop, however its changed slightly and I have other queries...

I've been testing a static caravan installation. At the plastic meter box outside the 'van (which contains an RCD, 16A MCB, meter and 16A socket for the caravan) I get a Ze of 20 ohms and 13.5A PFC. The earth is through the incoming looped SWA of 2 x 2c 16sq.mm cables (crude TNS from the point...
I'm doing an EICR on a static caravan after being called on to fix to a couple of problems due to loose connections.
It's all fine now within the installation in question but the earthing arrangement on the site is bothering me as it is relying on many multiple connections in steel armour...
Afternoon all,
I've been asked to add a socket to a brand new static caravan. I went and had a look last night, looks simple enough, its about 3m from an FCU fed via the socket radial circuit.
It's about 15 years since i've done anything on a static - that was an additional thermostat.
I'm...
Ever since I got the new van, or perhaps its a change of footwear, I am getting almighty belts off the van bodywork after I stop and get out.
Is there a way to minimise the crack, or use it in some "playful" manner?
First, a couple of questions i'm sure Marconi can answer.
Is it me generating...

Hi All
Looking for advice

Do you take it back to the nearest panel or take it to a earth spike ?
Ok. Static caravan.......
The site supply arrangement is apparently TNS and the static caravan uses this for its earth. (I will check with the DNO that it is aTNS arrangement.)
There are three MCBs in the static caravan CU, one of which directly supplies to a solitary double socket inside a...

We've had a few threads about phase converters recently. Here's one I repaired on Monday. It's a little box that takes in single-phase 230V and feeds a 3-phase motor wired for 230V delta. It includes a manual 'soft' starter and overload relay. Unlike the units in the other threads, this one...
