# Correct electricity set up needed!

Hi Guys,

Hope everyone is doing well,

I have issue with running my rigs 24/7, Im currently running 42 rigs at a usage of up too 84,000 Watts of electricity, I’m currently running on thin wires and planing to change that, if you guys can answer the following questions it would be great.

How much AMP’s do i need in total for my main circuit board?

How thick should be my wiring in MM for the main breaker to my small breakers?

How thick should be my wiring in MM for the connections between each socket? (to handle the heat of the sequence line of electricity usage)

Are your rigs 120 or 220,240V first question
What is your incoming voltage to the building?
single phase or 3 phase?
are you in the US? if so what city and state
residential or commercial building
are you using residential or commercial outlets 15 or 20 AMP?
is you device wiring in conduit or romex in wall?
what are the ratings on your PDU’s (Power Distribution Units) to each device if using any
what is your average rig watts (per Rig) and number of rigs this will help for branch circuit calcs
84,00 watts at 220V is 381 full load 24/7 a 400 AMP main service will not do because of the 80% rule it would be more like 600 AMP main.

you are running 24/7 you will need to account for the 80% rule I can help after you answer the questions

Hi thanks for the quick feedback

How do I know how many volts my rigs consume?
My incoming voltage to the building is 380V
Im using Single phase 10mm wires
I do not reside in the U.S
Im using residential building

We are running a rig with 2 X 1000 watts raid max power sources = 2,000 Watts per Rig X 42 Riggs = 84,000 Watts usage in total.

Hi thanks for the quick feedback

In my country the output is 220V
My incoming voltage to the building is 380V
Im using Single phase 10mm wires
I do not reside in the U.S
Im using residential building

We are running a rig with 2 X 1000 watts raid max power sources = 2,000 Watts per Rig X 42 Riggs = 84,000 Watts usage in total.

Are you sure you incoming voltage is 380V not 220V
or is it 380 AMPS?

In my opinion, the amount of watts used is not that important - and the most important thing to consider is the amount of amps you can consume - for example 100 Amps…

In the UK, if you have a house/residential property, you’d normally get single phase of 80 amps or 100 amps (at the cut out) at 240V. If you had a business property, you may get three phase of 100 amps (at the cut out) on each phase.

I’ve had an electrician do my setup (drawing currently about 270 amps across three phase) and despite it all being done properly, I had one phase go down due to an electrical short which caused a lot of things to get very hot. He checked it and said there was no way he was going to touch it and that it was a job for the distribution company (the company that look after the cabling infrastructure).

With the amount of watts you are using, regardless of how many volts coming into your building is something that I strongly advise you give the job to a qualified electrician to do - and let them work out the details to ensure your setup is safe and not likely to burn down… With the amount of electricity you are using, there are no second chances really.

Posing this Questions…

ONLY Solution: Get an Electrician!

Do not touch! In most countries it is illegal to do anything like this without proffessionals.

Just wanted to add that you should only be using 80% of your available amperage. To echo ehri, you should really hire an electrician to help you out.
