    Submersible pump testing

    Yup, the salty water is a far better conductor :) It's crazy when you think about those heaters. A body of water generally less than a bathtub. A cracked aquarium heater, internal terminals fully submersed, and then you top up the salt and stick your arms in. Result = probably won't even...

    Submersible pump testing

    The problem is that once it's failed sufficiently to give a tingle, the water is already causing a near total failure in resistance. Impossible to clear the water that has broken through so results will be highly erratic. In all events though, very unlikely to see more than 10k ohms achieved...

    Submersible pump testing

    I work in water display automation and often call in sparks to test kit ahead of going on display. It's amazing how many look for additional ways to test submersible pumps. It's as if you guys can't accept a simple days work ;) It's double insulated, the end. Test IR. That's all you need to do...

    Self employed electricians mate

    I stopped working on permanent installation due to CIS. Technically our work doesn't really qualify but so many site's started to have a uniform 'no CIS, no job' type rule and I got tired of arguing. In the end I became more specialised and ended up work in TV/Films/Events, safely away from all...

    My house was built in 1873 ish, what are the chances of asbestos being used.

    Very sorry to hear you had a personal loss due to this nasty material. The true extent of deaths related to asbestos back then is insurmountable I guess. But in both manufacture and use, in most guises it was dusty, messy stuff. It's somewhat shocking as I stand in the house we're renovating...

    Starting up to do weekend work

    Out of interest, what would you think the costs for capital to get kitted up are these days? And the what would you think the ongoing operating costs are? Just curious as I know a guy that does occasional work and he does complain that his insurance doesn't scale with turnover. He complains...

    My house was built in 1873 ish, what are the chances of asbestos being used.

    the average homeowner probably doesn't even know there is a dedicated survey. Most just have a general survey done, and on that the surveyor will just note the visible asbestos and a note/factsheet about how it's fine if left alone. I was myself genuinely surprised to learn just how many...

    Starting up to do weekend work

    My date rate + 30% for weekend work, unless it's part of a project running several weeks. If I'm honest I apply the same if it's a project I just don't want to do so much :) Then again, if this guy wants to start a new career with some weekend work, being one of the few sparks to be happy about...

    Motor starting from lighting switch

    Sorry I just realised I kept typing DOL in the enclosure, I meant the overload module. However, just had a quick google and this seems to do all you need, it is configured for remote control too: https://docs-emea.rs-online.com/webdocs/1586/0900766b81586128.pdf

    Motor starting from lighting switch

    0.8 kw = approx 1hp. The limit for no OL protection is indeed 1/2hp I assume this is an above ground pump? I would use a DOL module and if remote switching is required, use a suitable relay to carry out the on/off switching of the DOL module, in the same enclosure. I wouldn't switch power...

    Starting up to do weekend work

    Also a good idea to sort a basic, simple to use book keeping solution - gets tricky to make time for the admin once you're rushing around doing the actual work! Most basic packages have all you need to track business income/expenditure and print off/email quotes & invoices. Also a good idea to...

    Unable to find earth rod when doing EICR

    You asked a question, I answered. I never suggested anything about digging up the rod to inspect it. You're reacting very quickly to what you think I'm saying, please read more thoroughly. I also never gave any opinion on the c3. At any point. All I have stated is my opinion that as the rod...

    Unable to find earth rod when doing EICR

    I don't know why you would need to ask that question..? You have argued a somewhat minority view on this thread, and resorted to ever more peripheral technicalities to make your point. And now you ask me a rather basic question about the selection of electrode? Anyway, any type is fine so long...

    Highest paying specialty?

    I was saying to my mate that hopefully they could at least survive doing R&D and development work for other firms, as they always have. For some reason this made him smirk so perhaps they don't make as much from 'developed by Lotus' work as I thought!! Anyway, getting out of Caterham because...

    Highest paying specialty?

    I'd hurry up on the lotus. I was chatting to a guy who does a lot of automotive work the other day and we got to discussing how micro brands like Lotus can possibly survive the end of internal combustion sales. The problem being that development of a new electric platform is way beyond the...

    Unable to find earth rod when doing EICR

    Thanks :D To be fair, I think a lot of folk want to argue specific technical points on these forums - which is fine, I do it too. But on this occasion I can't accept there is any correct resolution other than starting by sinking a new rod. Any other debate about how to correctly evaluate the...

    My house was built in 1873 ish, what are the chances of asbestos being used.

    Or just get a cheap plumber round and encourage them to do a bit of electrical work... Joking. They won't need encouraging.

    Unable to find earth rod when doing EICR

    That's another angle that keeps being skipped as people try to compare this to other situations. This isn't a protected component... it IS the protection. We can all appreciate that houses get pulled around and often access to certain parts of the electrical installation are a nightmare...
