Hi,
I'm a little confused confused is someone can shine some light on the amendment 2 way of doing IR.
I know you have to do one 1st fix at 500V DC and then final one at 250V DC when all cables.
What I'm confused about is GN3 states:
"...sometimes these cables are terminated without further...
Hi guys and gals, I have a question about the leads to computers (commonly known as kettle leads).
I am new to PAT testing so please bear with me if this is a silly question.
I am aware that if a product has a particularly long lead then the result of the continuity test can come out larger...
I will start with apologies, as I have not thought this through very much (at all) yet and have just sat down with a beer.... meaning I thought I'd ask the collective.
CU change today. I did my pre checks and I knew I had a major IR fault on the cooker circuit (N-E 0.3ohms, yes that figure is...
This part is from a Mercedes prefuse box. I checked it for continuity by checking the two yellow marked wings and got close to zero. The part has a four prongs plug as well. What can I check to see whether the part works or not<<
Good morning all. Got a bit of a problem that is stumping me.
Called to investigate an external light not working. This light is on the same circuit as about 5 other lights and is controlled via a photocell which switches in a contactor to bring all lights on. Every light is working apart from...
Hi,
Passed my PAT test and have a new customer with 550 items to test. How do you guys go about testing everything? thinking back to my training they tell you you must test every socket on an extension lead and you must unscrew any plug that can be taken apart to check the fuse and the...
Hi all
Odd one today .. all 6 Hager rcbo's in a tn+n db have the test buttons not working..
But when tested with a multifunctiontester they react fine..
Now..I guess I'm going to have to fail them..even though they work fine.
Hager technical say they have never heard of this.
Db is in a plant...
Just your thoughts on this DB,it’s a Lewden type,I personally don’t like them.
Bus bar,not ideal,main switch on right,space very tight to make connections,hate the rcbo’s,screws in front of each other,making it hard to retighten .
We currently have LED lighting panels that are used for photography and video lighting purposes. They are a stand alone electrical device with their own power pack and mains adapter.
We want to have them tested by an electrician to see if they are safe, or if they have any problems. We are...
110v from switch to switch (see attached picture), tn-cs system with 30mA RCD in Place, trips fine when tested at 100% and 500% customer complained of getting shocked when touching both switches at once but doesn’t trip with this fault, have a few theories, but any suggestions?
Good points:
Loop test Hi & low Current only 0.02 difference
RCD tests very fast
Bad point : no earth spike kit with meter
Firmware 3.0
Could be the best Megger so far!
We stayed in a caravan in the last few days which had this fixed air blown heater underneath a wardrobe.
Inside the wardrobe the heater has a 13A mains plug with a PAT test sticker from 2012.
The switch on the front has been broken off and somebody has put in a block connected internally so...
Just installed a small length radial circuit. Total length from board no more than 2 meters. Halfway along is a FCU and a double socket at the end. Linked line and earth and tested at the socket and got a R1 R2 reading of 0.10 ohms,hit the switches to confirm polarity and the reading stays the...
Last year at night I was carrying out Electrical Inspection and Testing and Found the 300mm 4 core SWA sub main cable to a chapel was recording 0.09 ohms on carrying out high insulation resistance testing between phases. 25 thousand pounds later its rectified.
Would love to hear other people's...
