reverse polarity on appliance socket

[chris day]

Carried out an eicr and noticed x2 double sockets have reverse polarity that supply a frying machine at high level.
After correcting the reverse polarity on the two sockets i plugged the fryer back in and the circuit MCB tripped out and the appliance popped.

I am unable to open the fryer up as its fixed into the unit.

I cant seem to work out why the original appliances required the sockets to have incorrect polarity at the socket, and after correcting the reverse polarity the appliance tripped the fuse.

I checked the newly configured polarity and the sockets were correctly wired wheres before the L-N had been reversed.

What tripped CB,RCBO or RCD what instrument did you use to confirm correct polarity? looks like you need to carry out some more test on the circuit supplying the 2 twin sockets

What tripped CB,RCBO or RCD

Ow yes the MCB tripped

Ow yes the MCB tripped

Was the fryer switched on? at the fryer?

 

[Barnaby Stedman]

have you checked out the way that the cable for the fryer was wired into the frier?

Was the fryer switched on?

as soon as i switched the socket on with the fryer switched off it tripped.

Did the CB stay on without the fryer plugged in? and have you checked inside the plug top?

Without the fryer plugged in the MCB stays on, i checked the plug top and it was fine.

Fault on the fryer then, diagnosing from afar. As the job was an EICR thats, an inspection of the fixed wiring, which you have found and rectified a fault, your client needs to get the fryer tested under ISITEE the new way of saying PATesting, in my opinion.

if you are doing a EICR ,why are you correcting it ,c1 on the test sheet.

Probably agreed with the client to rectify any small easy to fix faults, that's an assumption on my part. But a very good point.

Sorry this was a return visit to correct the faults found

Sounds like you are the victim of a
Bodger who reversed polarity in 1st place !
--Appliance was faulty -But should have been tested before it was plugged in ?--

disconnect the fryers and tell the customer what you found and if so pull the fuse out of the fryers
