    Wago topjob current ratings

    Hello Can anyone confirm for me what the following spec for a Wago TopJob 2202-1201 din rail connector means? The connector can accept max 4mm solid core cable, so does this mean (see bottom row) the connector can cope with 32A? The row above says rated current is only 24A though? I’m easily...

    How to understand power ratings and interaction with fuses

    Hi there I have a few questions related to the power ratings of certain devices and how this interplays with the fuse. The reason I am asking this is whether I can safely add new plug sockets off an existing 3A fused spur (I plan to only use these plug sockets for low power devices). The...

    laptop power supply cables - fuses and ratings

    Hi there. I have noticed that most laptop power supply cables have a 5A fuse in the plug, but a 2.5A rating on the clover leaf end of the cable. Is this safe? Surely there should be a 3A fuse in the plug at least, given the cable is rated for 2.5A. The whole industry seems to be happy to...

    230v breaker ratings

    **DIY'ing a campervan, trying to plan the electrics myself before getting help to install so I understand what is going on under the hood. (Engineer by trade, can't help myself) Questioning my basic understanding of circuit breakers and plug sockets: If a standard plug is rated to 13A, do you...

    When do amp ratings matter

    Got some amateurish questions. Please excuse me but want to set this straight in my head. Do amp ratings only matter when current is being drawn i.e. an appliance plugged in, light fitting, etc. To expand, if I have a 50amp MCB with a 1mm T&E cable going into a 5amp junction box, would that...

    Bathroom zones and ip ratings

    I’m currently upgrading my bathroom suite and was wanting to remove the old style pull chords style switches for the fan and light for a switch. They will be mounted well outside the zone 2 area in the bathroom so do I need to take any ip rating into account as well. Many thanks

    Cable ratings - constant load?

    For argument sake, lets say a cable is rated at 100A clipped direct, ambient temp 30 deg. Does this mean it can take a constant load of 100A in those conditions or is the rating based on cyclic current? The reason I ask is on a recent install, following current cable guidelines we fitted a 35mm...

    Description of IP ratings in BS 7671

    Hi Can someone point me to the description of IPXXB and IP2X in BS 7671. I know what they are and the requirements of each of them are, but I cannot locate the description in the Big Blue Book. Appendix 5 on page 450 has the details of IP 0, 3, 4, 5 & 6X but not the other 2. Cheers
