    Hello All,

    I am in the process of buying a house which needs a little work. All of the electrics seem to be ok except for a few sockets that are loose.

    I am wanting to get a tester that plugs in to the socket and tests the wiring of the house.

    I have had a look around and there are loads of different ones and i am getting a little confused as to which would be the best option as they range alot in price.

    the ones i have currently seen are linked below

    Any advice would be really helpful

    Thank you

    All they do is check that there is power getting to the socket and that the wires are connected to the correct terminals. A potentially dangerous installation could still light the correct lamps.

    It doesn't test the condition of the wiring, insulation, overload protection or efficiency of the earthing. A proper test meter (or meters) and the knowledge to use it properly are required to test an installation properly.

    For an insulation and continunity meter, click here

    For a meter with earth loop and RCD test click here

    There are a whole range of testers but you do want something that does a loop test. [​IMG][​IMG][​IMG] all do some basic loop test. However it is only a basic test. The meter will tell the trained tester a lot more.

    For example I did about 4 sockets close together and noted that the readings were more like those expected for sockets dotted around a whole house and I flagged there must be a fault. There was a potentially dangerous fault likely to produce a fire if for example a kettle had been plugged in. Looking further I found 0.2 ohm resistors had been soldered onto the wires between the sockets. It was in fact done to make the 4 sockets emulate readings expected in a house and was a test rig for testing students but my experience and knowledge plus using a meter able to measure that resistance enabled me without tools to flag up a fault.

    The best of plug in testers give a 0 - 1.7 ohm for first light since the fail mark is 1.44 ohms it clearly will not flag up the fault I related to. However it seems there is a huge jump in price from approx £40 to £120 for one with a reading like this [​IMG] since it needs some skill to use I would say likely better to pay for a proper test from an electrician than pay that money.

    Remember there are another two meters required for full test a special low ohm and insulation tester and a RCD tester. Remember less than 50% of electricians pass the C&G2391 exam first time even after special training. So it is very unlikely as a DIY guy your going to do the job correct.

    The solicitor should have advised you to get an electrical installation condition report EICR was called PIR (Periodic inspection report) I know many don't bother but £4000 for a rewire is a lot of money and many a pre-1960's house have no earths to lights for example so really should be done. You have no idea what DIY may have been already done and loss of ring on a final ring circuit, for example, is a fire hazard.

    What about the IR tests? any plug-ins that do that?
    You could hire a MFT for a week, for the price of one of those socket testers!
