So I’ve recently started my level 3 course and I’m doing electrical system designs the one with the hotel extension and pool and cafe block I’ve done question 1 but stuck on all of question 2 some guidance would be appreciated thanks.

Can you send to me the drowning pleaseHi John,
I'm currently doing the same project.
The hotel rooms are like premier inns rooms. sockets either side of beds, 2 double socket on table for tv, kettle etc & socket by the sofa, heater fcu by the door & towel rail fcu outside of the bathroom.
CU in each room by the door.
when i get back home i'll convert my visio file to pdf & pm you so you can take a look.
maybe we can buddy up on this & throw ideas about?
Michael
Can you send to me if you have more
I stack with this pleaseCan you send to me if you have more
What is it that you're struggling with specifically? I don't think anyone would possibly give you a completed hotel assignment (that not what you're asking for I know but in putting it out there).hi, im currently trying to squeeze my level 3 hotel design in before christmas due to lack of time with covid, anyone have any pdfs of previous work that i can follow as a guideline? much appreciated
Think about it logically;I’m stuck on questions 10... seems quite straight but struggling none the less. Anyone able to help?
This is great. I need a greater understanding of functional switching will need to read up on that. What’s an example for further requirements?Think about it logically;
Isolation for maintenance; well that just screams plant room (hazarding a guess at the location of this assignment - Swimming pool?)
Switching for mechanical maintenance; again this screams to bear near any machinery or plant
Functional switching; every room/area within the complex to some degree
A light switch to start with...I need a greater understanding of functional switching
im the same john stuck on question 2 a 2b right to 2iSo I’ve recently started my level 3 course and I’m doing electrical system designs the one with the hotel extension and pool and cafe block I’ve done question 1 but stuck on all of question 2 some guidance would be appreciated thanks.

Show us what you have and we'll steer you in the right directiondoes any one have any completed or part done plans for the 2365/5357 drawings to see if I am doing it right
Easy method, use the adiabatic equation to find out the sizeI’m suck with the question attached 615 2365 electrical design project ? question 5 2 hours still can’t work out the answer
Thanks for this it’s just different this level 3 as I’m dyslexic not with reading and writing but with maths and new things of of my comfort zoneEasy method, use the adiabatic equation to find out the size
S = ✓ I^2 * t / k
I = the current required to operate the device
t = disconnection time required for the device
k = factor given for the cable selected - Typically 115
So for argument's sake, let's say we have a fault current of 320 (taken from your trip curves) a time of 0.1 (taken from your device operating times) and a K factor of 115 (taken from the tables following the trip times)
S = ✓ I^2 * t / k
S = ✓ 320^2 * 0.1 / 115
S = ✓ 102,400 * 0.1 / 115
S = ✓ 10,240 / 115
S = 101.19 / 115
S = 10.05
As there is no conductor with a CSA of 10.5, you select the next size up, in this case 16mm^2
The above is purely and illustration and values may not be accurate but it serves to show how to lay out the equation so that you can understand what is going on at each step.
Hope this helps
Dyscalculia you mean? ?Thanks for this it’s just different this level 3 as I’m dyslexic not with reading and writing but with maths and new things of of my comfort zone
What you struggling on? Show us what you have and we'll offer some guidance.im doing this assignment right now honestly i think its mental who thinks of this ----
Hi,What you struggling on? Show us what you have and we'll offer some guidance.
Ok, easy;Hi,
I don't currently have any pictures but I've drawn out on the hotel rooms how each would be wired for what the spec asks for. After reading through and breaking down the task sheet and looking around the forum I am beginning to understand this more taking it a bit at at time. I have less than 2 weeks so I was in a bit of a panic.
This is a question I do not understand
"Select, with the aid of manufacturers’ data, a suitable range of circuit protective devices for this
contract. Your selection should be based on the following
Prospective short circuit currents
Requirements for additional protection and special locations"
