Electrical safety and Firehazard question

[AmioriK]

hello everyone.

Since i am now very dedicated to crunching/folding 24/7 with many machines and equipment, I have a question regarding Fire Safety, and Electrical Safety of my farm, as it is on 24/7 and may not always be supervised. So obviously this is extremely important for me.

Question 1; Power distribution set up safety/good practices, is this acceptable?

In order to explain my current Farm / gaming set up, i have drawn (albeit poorly xD) a diagram of how i have all the electrical set up. I have everything connected to 1 Wattage meter as I only have one and i want to measure the entire farm. Here is the picture:

Is this safe for 24/7 use with no considerable risk to fire safety? Thanks.

Question 2; using multiple Molex -> 3-pin Fan adapter connectors

I am using multiple molex -> 3 pin fan adapters in my Folding rig with 1200 and 1660. As the motherboard doesnt have enough fan connectors and i have run out of splitters. is this safe for 24/7 operation with minimal risk to creating a fire hazard or electrical hazard (ie. blown psu) ?

I heard that some of these connectors can catch fire / burn out but I have conflicting information. I think 2 of the connectors run off 1 molex here and 1 off its own molex. power use of the fans is very low (they are quiet/low power).

I'm just anxious that i'm putting our house and our lives at risk by doing this. Any tips / advice to creating a safer set up would be much appreciated.

thanks

thats because some splitters, extensions and connectors are garbage and some are not. I'm not sure they specifically have anything to do with current draw. I'v seen members post pictures of simple things like extenders, or molex to SATA converters that just catch fire and melt.

Ah i see. Well these are cheap ones that came with Scythe Gentle Typhoon fans. Do you think it a better idea for something like this

i use one in my main pc.

Or would the molex's be okay? here's a close up. (BTW I pushed the little pin on the 3 pin back in lol, it came out a bit Rip).

Do you have any thoughts on the power cord setup also?

Everything being run from the one wall socket?
Nah, what could possibly go wrong.
Try to distribute the load over a couple of wall outlets if you can, even if you need to purchase more power meters to check consumption.
Having everything from the one point may exceed the Amperage draw available.

It likely doesn't matter as he appears to be only pulling 750W from the wall (does seem low) and it is a 240V outlet. 750W coming off a 240V circuit is only 3.4 amps. Assuming he is wired to similar standards as the US, he likely has 14g wire which is rated much higher than 3.4 amps. He could easily pull double that with no issue (yes, lots of assumptions about wiring but that is all I have).

On to of that, the whole room is likely powered by one circuit/breaker so the only thing he would be doing is spreading the load off the wall outlet which given this load is not a factor. That said, it doesn't hurt to spread it out either.

1. I never use splitters, fan hubs much safer and waaaaay cleaner. Also, these are quality units.... splitters range from good to crap to terrorist threat

For PWM fans use one of these
http://www.swiftech.com/8-WayPWMsplitter-sata.aspx

For DCV fans use these
http://phanteks.com/PH-PWHUB.html

If using PWM MoBo Header, use as many fans as ya want (up to 11) with STA power cable connected
If using DCV MoBo Header, can use about 6 fans just make sure total amps < 0.83 amps to be safe on 1 amp rated header. Do NOT use SATA power cable or fans always at 100%

2. Grab one of these to see what you pulling from wall .. just plug ya power strip in.

And it's not how much is plugged into that socket ... it's how much is plugged int the 6-8 outlet boxes on that circuit.

Tho gotta ask ....farming is dead here in US and out electric cost is about half yours.

All that on one outlet is probably not a good idea.

The less connectors total you can have for everything the better.
If you must use them at least make sure you don't have too many on one branch of the circuit or you could overload the plug closest to power source since it would have to carry all the power demand(s) for each component behind it in the circuit. Melted plugs can and do happen, I had one do that last week in my cooling tower and was only from a single 120cm fan (240 CFM Delta).
Yes that one has alot of amperage draw for a 120cm fan but proves the point, if a singular component like a fan can do it branching off of plugs for components in a circuit after a single power feed plug can do it too.

Thanks for the input guys. Taking everything into consideration I am going to remove the dual socket 13A extension cord and plug each surge protector into its own outlet.

And I'm going to remove the fan molex adapters and use the hub as suggested.

Do you think it is worth grabbing a 3rd surge lead to take 6 plugs off my 12 socket tower, split them between two outlet?

I didn't consider the rating of the cord wires, but I assume as it is fitted with a 13A fuse it's good up to around 3kW?

Thanks
