Dedicated earth on fridge compressor

[Mr Midlife]

Hello,

I have a quick question...I have been asked if the compressor on a fridge requires dedicated bonding to the body of the fridge? Currently they are not and they pass electrical testing. Does it actually require earthing to the body?

Thank you

Hi - are you saying the compressor is connected to E and the metal fridge frame is connected to this somehow, but you can't see an actual earthing conductor joining the two? Or ...

 

[telectrix]

quite likely that the frame is earthed to the compressor via the pipework.an earth bond test using the frame for the earth would confirm

 

[Mr Midlife]

I guess what i am saying is, does the compressor require a dedicated earth to the fridge body? currently they do not have dedicated earth bonding, and the fridges pass the earth bond tests all the time

EDIT:
and thank you for your responses too

If you test just to the compressor does it pass?

Is this how they are manufactured.

 

[Mr Midlife]

FYI i am using a pat tester, and i usually stick the earth bond cable on a pipe on the compressor as its the easiest pace to get a good connection

 

[Mr Midlife]

they are manufactured in poland without the dedicated earth bond.

some other fridges we have do have dedicated earthing from compressor to fridge body

What testing regime is the fridge passing?

Then test using the fridge body to prove the earth bond

 

[Mr Midlife]

the fridge is passing the earth bond test, its passing the load test and the insulation tests.

I have used the fridge body before and they pass, its just it was easier to use a compressor pipe.

ill use the body next time (usually on a screw used for bonding a lid to the fridge)

Good man

 

[Mr Midlife]

ok, i just tested one that has passed previously, i used the body of the fridge and it passed again

 

[Mr Midlife]

would the earth bond test fail if the compressor was not earthed? is the compressor not earthed through the earthing on the power cable?

Most fridges will be connected via a 13Amp plug and the earth continuity linked to all metal parts, at least they should be.

 

[Mr Midlife]

so performing the earth bond test on the compressor pipe confirms its earthed, and doing it to the fridge body confirms the body is earthed. does that mean it doesn't need a dedicated earth bond from the body of the compressor to the fridge body?

Where does the flex from the plug connect to on the fridge?

Where does the flex from the plug connect to on the fridge? Not sure what you mean by a "dedicated earth" all metalwork on the fridge should be earthed via the flexible lead connecting it to the socket.

down the bottom, round the back. .

 

[Mr Midlife]

this is what some of our fridges look like, whereas the ones i'm working on do not have this earthing bar and earth cable.

is this a little over the top?

The compressor may be double insulated.
