As per title, what code do you think is applicable when a 63A RCD has a 40, 32, 6 & 20A breakers?
And gas not bonded but was required at time of building (2012) although not now?
I have 2 consumer units, one normal and one for t control, I no longer have storage heaters so want to get the meter removed, can I then use the consumer unit to supply the sockets that were originaly used for storage heating, my immersion heater is also connected to this consumer unit so that...
My 50 amp breaker at the bottom just tripped I’m trying to figure out why. Is there too many amps being pulled in the house? I don’t use that top Left 50 amp breaker.
the 50 amp is wired with 6/2 wire to a sub panel that pulls 8000 watts. It’s definitely oversized. The project called for 40...
Hey, I'm an electrical engineer in training and i was wondering how you could calculate the total resistance in a series-parallel circuit? I attached a picture of what it looks like. If it's to any help resistor 1 is 2, r2 is 3, r3 is 4, r4 is 5 and r5 is 6 Ohm. Thanks for any help
Hi all I am having trouble trying to work out the total load and swa cable size.
I have 10 circuits in a outhouse 40 meters from the mains power supply 1 x lighting with 10 lights, 1 x lighting with 10 lights.

hi all,
Quick question I hope you can help me with, it’s to do with VIR triangle, and in this case how many amps pass through the circuit.. so..
If a human touches a circuit with 100,000 ohms resistance of the skin, and the voltage is 240 volts, does this mean the individual gets hit with...
A client wants five new commando sockets, seeing as you cannot apply any diversity to the commando sockets would i be correct in saying the below will need to assume a maximum consumption of 96a from a 3 phase supply, so as a bare minimum the power supply specific to these circuits would need to...
just a weird one here. driving along, slow, in traffic, suddenly warning comes on " tryepressure system fault", then power steering fails, then IBIL roigh sensor fail" then RBIS left sensor fail, then engine stalls, won't restart. stuck in left lane of dual carriageway, hazzards on but still...
Anybody heard of these people? I've received emails offering exclusive contract works in my area on a contract they claim to have? Looks and smells like a scam to me but wanted to know if anyone else has heard about this?
hi all small formula issue can anyone help got the basics can add, multiply, ect copy columns, but need a multiple column (sum) entry.

Hi all,
Looking at replacing kitchen. Current setup is 2.2kw oven, 5.6kw hob.. total = 7.8kw on 6mm cable, back to a 40a breaker. The current cable run is short..
2m from CU, in breezeblock/plaster..
2m clipped direct, to a 45a switch (for oven in tower)..
3m spurred from that, on...

I got a call from a lad who runs a snack shop asking why his fuse kept 32 amp fuse kept tripping . I went to the shop to have a look he has a total of 20000 watts (100 amps )on at one time with fryers, hot plates ,grills etc ! All single phase . Having little experience myself as a spark I...
I've been looking for somewhere to get a qualification in Voltage and Current Harmonic Testing to help with Ultrasonic testing.
I want to use this along with Thermal Testing to help with periodic inspection & testing on installations where its not possible to do any dead testing.
I just can not...
Hi All
My trusty old SMEG fan oven has finally died and i have been offered a replacemnt, brand new, never fitted at a good price.
