Hi I currently live in a home with a 15/45 amp meter. It’s a fairly new house.

 

I have some computer rigs that I use to mine ethereum(like Bitcoin).

 

I had a sub breaker box installed in the bedroom with 2x 30amp breakers which I was using and have everything plugged into.

 

I have just bought some more rigs and want to use a total of 50 amps for the computers and need maybe another 5-10 for the house.

 

can I draw all this with my 15/45 household meter?

I asked the pea if I could upgrade to a 30/100 and they told me no.

 

thanks

That would need an upgrade. 

You can get 3 phase. 

A 15/45 is officially 45A max.

 

Many run these on a 63A breaker with no issues.

 

If you go over 45A there's no guarantee of accuracy (bet they don't read low) but the meter itself is pretty bomb-proof, a 100% overload (90A) isn't going to kill it.

 

As noted above, go 3-phase and get 3 x 45A!

 

50A @ 220V is 11kW all of which will end up as heat, how are you cooling this lot? I'd expect you to be using about 3kW on cooling for these rigs too.

Just a side question: How much do you think your electric bill is going to be VS take home profit? 50 amps is a massive amount of draw and run for any significant amount of time would put your electric bill into the 20,000 baht range or more. 

I’m cooling them using 3 extraction fans to suck all the heat out the windows, managing for now yea prob pulling 2kw on this.

 

my monthly electric bill is roughly 25k baht but I’m pulling in around 160k baht from the mining so good profit for now

 

how much would it cost to get 3 phase installed? It’s a pretty normal village I live and the house is rented

11kWs ... MEA is about 4.2thb/kWh ... running 24hrs and 30 days might be just a little bit more than 20,000baht.

You will need to talk to PEA and your landlord about installing 3-phase. Along with a contractor to do the actual wiring for you.

 

What mining hardware / software are you using? We could support one or two miners from our solar without doing nasties to our PEA bill. If the return is really in the area you suggest I might consider a spot of crypto.

 

I’m just using graphics cards a mix between 1660 supers and rx 580’s all mining ethereum, bought most from shopee and Facebook 

 

a typical rig has a motherboard with 6-8 pci slots and basic cpu and 8 of these cards, a typical rig costs around 130k baht but generates 18k baht a month of ethereum (at today’s rates) and costs 2-3k of electric giving 15k profit so about 10 months to get ur money back plus u still have all the hardware after, took me about 2 weeks of learning everything crypto and mining related to get it all going then just grew it from there as many people estimate ethereum will go up 2.5x in Price over the next year , would be happy to share more of what I’ve found if anyone is interested, in total I’ve spent £35k now on equipment and I’m pulling in £4k a month once I get my new 4 rigs plugged in,

 

so just to be very sure, pulling 60amps (14kw) on a household meter 15/45 is still safe?

Usually, the meters can be overloaded for certain time. And your load might not be always on the maximum

OK, it's probably not going to burn your house down (assuming we have a sensible installation), but a constant 60A on your 15/45 is going to be noticed by the supply authority.

 

Whether they actually act on that or not is debatable of course.

I think I’ll rent another home and split the rigs 50-50 between here and another place as I don’t want too many eyebrows getting raised, I wrapped one of my racks in silver foil recently and the neighbours must think I’m building a spaceship to go to the moon (which I am hoping the crypto will)

 

thanks for the advice

Maybe do a cost-benefit analysis of buying a quiet diesel generator with a high duty cycle.

In addition to what Crossy has said, I will add that pulling a continuous 60A from your existing power supply equipment could well cause you problems with overheating and burnt out connections, this especially knowing Thai wiring conditions here.

And the lottery numbers on 1st November please!   LOL
