It looks like a standard RSJ measuring tape as used by apartment developers in NSW :laughing1:

There is a divide in convention between hobbyists and professionals. In professional audio and telecommunication applications a coloured, marked or striped conductor is almost always the 'hot' (+) or 'active' wire of a pair, in fact I don't recall ever coming across and exception to this rule; in non-professional circles the marked or striped conductor is commonly ground or (-) with an exception if the marking is red. Being from a professional background, I always use the physically striped...

When AC is switched, any arcing self extinguishes when the polarity reverses. But for DC with no polarity reversal arcs when they occur persist much longer and burn more metal off the switch contacts on each throw. A switch used for DC will burn out much faster than if it is used for AC at the same current. Best to choose a switch with a DC rating if its for a critical purpose. But to the dog's original question, an architrave light switch or inline 240Vac power switch would be fine for 12Vdc,...

A B22 plug to an AS/NZS 3112 socket would not be 'legal', but no problems with cutting off the AS/NZS 3112 plug and replacing it with a B22 plug unless an earth is required.

I am not familiar with the seals. Raven Australia likely made the seals or have a suitable replacement. https://www.raven.com.au/

Been here all along, just haven't had anything to contribute. Life's been good and since we have everything we need here, thank you, and our lives and home totally unaffected by Covid, lockdowns, shortages and bureaucracy. No petrol to buy, no electricity or water to pay for, don't even need toilet paper with a $27 bidet bought from Vietnam on fleaBay. And no, it's not time and/or money that gave us this, but simple choices that anyone can make. The only requirement is to abandon wilful...

This is the "standard" Apricus setup for evacuated tube SHWS with gas backup, showing all regulatory safety requirements common in Australia:

Besides controlling the circulation pump, most solar HWS controllers have programable (time of day) outputs to control a backup heating element. The element will still only kick in if the water is below the tank's thermostat setting. An instant gas (flow-through) heater is the most efficient, common and simple solar hot water backup for inclement weather, and usually can be left switched off except for winter. Instantaneous electric water heaters are also possible but usually draw heavy...

I installed an evacuated tube collector and controller to an existing 'standard' 250 litre electric storage tank some years ago, and disconnected the heating element. After watching the tank temperature plummet overnight, I insulated the tank and built an insulated enclosure around it; now the tanks holds its temperature overnight. I do not have any backup hot water heating and we have not run out of hot water for the past few years even during extended cloudy periods (two adults). I think...

There was enough science to start mass producing renewable energy equipment in the early 1970s, but the market dominant energy monopolies fought against it tooth and nail back then just as they still do today. The only reason I could think of way back then was that big business and their guvment lackeys don't like monopoly breaking renewable energy, where thousands as much energy as we can ever use is falling around our ears every day waiting to be put to use. Instead of encouraging...

Where does 40 years come from? 165 years ago in 1856 the American Journal of Science and Arts published experiments documenting the heat trapping effect of CO2 gas in the sun's rays. Nearly 150 years ago in 1877 Boltzmann's constant, the application of which determines how much warming atmospheric greenhouse gases cause, had been calculated to a degree of accuracy that hasn't changed to today except in decimal points, and by 1896, 125 years ago, it had been estimated how much warming a doubling...

I can't imagine what you think of axe murderers who steal their murder weapons...

Great idea! I'm not so sure you are going to save much time over a well thought out removal and making good of the entire spa. A few points: the 50mm lip will absolutely be a trip hazard - don't do it; the narrow entrance will also cause falls when feet or shins accidentally touch the sides, make a 600 minimum wide opening (based on OHS access requirements from years ago); provide a grab rail or handle on at least one side to assist with the transition; make sure the bottom of the tub has...

:2tsup: That's not what Ted said... :roflmao:

Your reservations about the vendor and the product noted, ethically and morally you should not expect entitlement to a refund if you do not return the item to the vendor. And you most certainly should not consider keeping the item if you receive a refund via PayPal prior to a return - it is the relevant authority's responsibility to prosecute the law, not anyone else's.

Stormwater entering sewers is a major cause of treatment system overload and consequently public health standards being breached as untreated waste water is released. I have heard that injecting smoke into the sewer system is sometimes used as a means to detect illegal stormwater connections or other breaches of the sewer system.
