What does "recs" mean? I understand the rest. When you say "best", does that mean it is a recommendation, or is it part of the IEE regs? What does this mean? No, it gets filled by a hose pipe, the electricity is used to feed a heater and a pump. Does this affect whether or not I need an...

I have dug out a domestic electrical installation certificate for the property and it says the 'System Type' is TN-C-S. It also says that the 'Means of Earthing' is 'Supplier's Facility'. Can anyone tell from this if I need an earth spike outside? Which system's would need one - and why...

I can't tell. The CU is mounted on a plasterboard wall and all other wiring is concealed behind the plasterboard. I presume that if there was supposed to be a notice it should be obvious. The only notices that I can see are on the CU. One mentions the RCD and talks about testing it with the...

Thanks for your reply. I don't know. The supplier has not shown me any electrical specifications, except to tell me that I need a 32A/32mA RCD circuit with an IP56 isolator. You make a good point, and this is what I have found looking at tlc-direct's web based calculator. This distance is...

I am having a 32A outside circuit fitted from my consumer unit to power a hottub. The cable is 6mm armoured, and about 40M in length. 1. Is there any IEE Regs requirement to use an earth spike anywhere in this circuit. If not, why do you think the hottub supplier may have recommended that I...

thanks for your reply. Is there a limit to the number of MCBs an RCD may feed? Is this a physical constraint of the consumer unit, or is there an imposed power limit. I have four or five MCBs which appear to be associated with the RCD. There are spare slots in the consumer unit - is it...

in part-reply to my own post, I notice that my consumer unit (new build property) already has a 30ma RCD fitted. Can I assume that this protects all circuits fed off the consumer unit? If so, all I need is an MCB. Assuming I need to be able to deal with a 32A load, could I get away with a...

Sorry if this topic has been done to death already, I did a search on the forum but could not find what I wanted. I need to install a power outlet in the garden and have been advised to use a 32 A circuit - comprising of 6mm armoured cable a 30ma RCD and a 30A MCB. My question is in...
