many chinese led factory use same cable for all voltage range seller info show input = 12v seller has no info about dc or ac many led circuit for outside light allow 12v ac or dc possible if dc only brown = + blue = - green/yellow ground to metal body seller info snip

possible these are scale reducer

fun with bare element heater sometime called suicide shower some idea about how the steibel product can protect user from the dangerous current resistance of water at shower flow tube makes current limit to water output also show problem with rcd device using this heater type some suicide shower video part 2 show the leaking current test part 2

my english is not good but not difficult to understand for most people out of wack i need the lookup ----------------------------------------------------- ---------------------------------------------------- best if you make the contact with steibel company about this out of wack info web link to stiebel company writing i copy at my post https://www.stiebel-eltron.com/en/home/service/faq/what-heating-systems-are-used-in-instantaneous-water-heaters.html tech document for bare wire heating element 23_Janzen.pdf

many steibel 3 phase heater have bare type heat element possible some country have the special safety regulation require for this type system i think for sure good ground is important and best include some earth leak protection at supply some information about bare wire heater from stiebel company The water in an instantaneous water heater is heated either by a tubular heater system or a bare wire heating system. Most STIEBEL ELTRON instantaneous water heaters heat water using bare wire heating elements. The live heating conductors are located directly in the water to be heated. The bare wire heater spirals are set into a pressure-tested insulating block. Pipes in the insulating block house the heater spirals. The insulation resistance is assured by upstream and downstream devices, even if the earth conductor is interrupted. The insulation resistance depends in part on the properties of the water flowing through. For this reason, the electrical resistance and conductivity of the water at the installation location must be taken into consideration. Bare wire heating elements are also especially suitable for use in hard water. The very small amount of water inside the appliance and the low-mass heating system mean there is hardly any post-heating after the appliance has been switched off – an important factor in the reduction of scale build-up.

possible steibel use same heat core for low and high power model high power model have 4 element in the star low power have 3 element in the star here is circuit for high power model

interesting why you waste time asking many question at this forums i made support to my post with university paper on this subject if no time to read paper best not comment ************************************************************************************************** thank you for this reply i try to fact check my tech knowledge before post most forums have mix of good knowledge people and those who try help and people who make garbage best idea to pick through posts and make own internet research if important this subject of dc breaker is important for good safety and good if diy solar people understand danger i sure if people post bad info in this safety topic tech people will make correction

thailand owl not sure type possible expert can help

information from car group forum translate from thai to english 2008 ford ranger 2.5 TDCi bosch injection pump number We0113800 cost 20000 to 30000 baht

sometime is best to keep simple explain not all people need detail paper for detail this paper help understand why some of the polarize breaker fail if connected incorrect energies-15-02776-v2.pdf

electric arc can move with field of magnet polarized breaker has magnet to direct arc into safe chamber if polarity not correct magnet will push arc to the incorrect direction and are will continue burn

from other people yes for bill no payment yes for cheating meter connection found with photo from meter read worker yes for modify of feed to many house yes for argument with pea engineer meter removed for days making big problem for customer

sorry not me for hire but can find some free info at my youtube channel

possible there is no fine if cannot prove any cheating but biggest problem is to find electricity meter missing with no warning made after this the bigger problem is time to have meter and power back in home nice to make some jokes about this but pea can make the life hard work guess is up to you good luck with choice

when meter has seal maybe best find pea worker to help with this most time there can be no problem cutting seal but sometime meter has seal for reason meter reader has flag on his reading computer for suspect meter and often take photo update big change in use can sometime start suspect meter flag in pea computer if you sure seal fitted when meter first time installed possible no problem cutting the seal

wago electric connector use lever clamp system for connect telephone type connector most use insulation displacement contact type many high standard accessory in the world now using fast connect lever and spring type

smart meter have the impulse kwh indication this can show if energy is metering number of impulse kwh is on meter label electronic circuit of the meter take power from input side for some info about power directions and smart meter youtube can help here is user book for smart meter 2020-11-04_104726_Download.pdf

some search using text from other post has good results MK K2737WHI 13 amp 3-Gang Double-Pole Switch Socket more detail show it is 3 ways socket with protect fuse and is british standard product good photo

thailand supply store for electrician have switch 4 way type sometime have other name like intermediate or changover type panasonic WEG5004 is example

New AC has the refrigerant pre charging at the factory in outside unit If line length under standard no need for install worker to use refrigerant daikin model FTKZ-VV2S has chargeless value at 10 meter r32 refrigerant is in thailand for some years ac tech understand system use different refrigerant if this makes a big worry check refrigerant tank used by install workers if they require some line top up

What do you not think so? I make no mentions of the blue sky or promise and make no comment of catl I only make suggest that best wait for product applications before using in the argument. You sound very confuse maybe take some relax rest for short time

Like i already say we wait for real world ev car application of better improve battery then maybe everyone can have a celebration I know the 3 big china battery company because we make some special laser cut tool for byd case production I read often the tech papers from battery maker in china My english translate assist app tell me you make the split hair argument

Yes but i already say we must wait to see the practical application before using in argument Many super bus battery on operating test but not in real world application Using idea for future time in real time argument always bad idea

Thank you much for this but i ask for example on roof of shopping mall not office with space limit Never mind i understand this not easy find Some more research show roof is not popular place for big power transformer. many engineering + logistics reason for this Is nice to read about future plan for super battery and fast charge but best to see wide uses in real world before making these idea in argument for ev car Some of ev super battery idea come from ev bus battery research where bus can make fast topup at park station on route. this lots more easy than the fast charge service for million cars
